WuWa 4.0 leaks have gone from a trickle to a flood over the past few weeks. The theory everyone is converging on: the whole 4.X arc belongs to the New Federation, the cyberpunk nation that Calcharo, Mortefi, Lynae and Verina come from.
Lily's official profile already drops her into the Federated Cities' Resonator War, which makes Version 3.8 the handoff and Version 4.0 the chapter that opens the door.
And 4.0 is not shaping up like a regular patch. Two new Resonators are attached to it, Anna in the first half and Lucille (also spelled Luxier) in the second, plus a new map, a flying vehicle sitting in the game files, and a reworked Tune Break system.
Below is the most complete set of WuWa 4.0 banner leaks anyone can put together right now: banner order, release date, rerun candidates, the New Federation map and the new combat mechanic. If you are mapping out WuWa upcoming banners past 3.8, this is the one to bookmark.

WuWa 4.0 Banners at a Glance
4.0 is the next banner cycle after Lily, and the roadmap sticks to the familiar two-phase split, one new five-star per half. Anna opens the version and looks like Rover's way into the New Federation. Lucille arrives in Phase 2, tagged so far as a Fusion sub-DPS.
Every table below uses the same four labels, so you can tell at a glance how much weight a line deserves: Repeated leak means several trackers agree, Single leak means one source, Speculation is community inference, and No data yet means nothing has surfaced. Official is reserved for anything Kuro has actually confirmed.
Rumored Phase 1 Banner: Anna
Anna is the steadiest name in the entire 4.X leak pile. Roadmap summaries keep putting her right at the start of Version 4.0, and the newer descriptions plug her straight into the New Federation's power structure rather than some side faction.
A first-half slot also matches how Kuro has opened every region so far. The Phase 1 character sells you the setting, carries the opening story, and shows off whatever combat system the region was built around.
Rumored Phase 2 Banner: Lucille
Lucille shows up on the early 4.X list and is currently pinned to the back half of Version 4.0. The one gameplay note anyone has on her calls her a Fusion sub-DPS, and that is the only role hint either 4.0 banner has right now.
An early team concept pairs her with Hsin and Suoming. That sounds less like someone replacing Hsin and more like a unit that tightens the rotation through off-field damage or a useful Outro Skill, which is how Fusion sub-DPS units usually get built.
When Is the Wuthering Waves 4.0 Release Date?
Short answer: around December 23, 2026. Kuro has not announced anything, but the patch cycle is regular enough that the date is easy to work out, and the beta and broadcast dates fall out of it too.
WuWa Upcoming Banners: Phase 1 and Phase 2 Estimates
WuWa has settled into a tidy 42-day version cycle, and that is the backbone of every Wuthering Waves 4.0 release date estimate. Working the cycle forward gives you three dates to plan around.
When We Actually Learn More: Drip Marketing, Beta and Broadcast
Lily's WuWa drip marketing hit on October 7, roughly five weeks ahead of her banner. Run the same gap forward and Anna's reveal should land in the second half of November, which is the post where her Attribute, weapon type and rarity stop being guesswork.
The 4.0 closed beta would follow in late November or early December, which is when Forte Circuit, Resonance Chain and signature weapon details usually leak. Then comes the Version 4.0 Special Broadcast in mid-December, with the final banner order, reruns, events and redemption codes.
Anna in WuWa 4.0: Leaked Identity and Role
Anna has no official art, no Attribute and no kit, so everything below is leak territory. What she does have is a consistent story role, and that tells you more about her value than a stat line would at this stage.
?
Who Is Anna? The Noble-Family Leak Explained
The description that keeps coming back calls Anna the daughter of a noble family, putting her inside the New Federation's aristocracy. Later posts added the detail everyone latched onto: long white hair in twin tails.
A separate reference image of a military police instructor has been floating around the same 4.X list. Some trackers pin it on Anna, others say it belongs to a different character entirely. Until official art shows up, the noble-family line is the safer bet.
Either background suits the job she seems built for. An aristocrat gets access to the people actually running the Federation, and Mortefi's profile already confirms that upper class exists, so Anna would open doors Rover cannot open alone.
Anna's Rumored Rarity, Attribute, and Combat Role
Opening a major version almost always means a limited five-star, so that much is safe. Her Attribute and weapon are completely blank, though, which leaves Kuro free to build her around the New Federation's combat identity instead of patching a hole in some 3.X team.
The exciting possibility is that Anna becomes the first driver for the region's new mechanic. Lahai-Roi pulled this off with Off-Tune in Version 3.0: the opening cast taught you the system, then stayed relevant in endgame content for months.
One warning about the leak list itself. The vampire femme fatale concept drifting around the same 4.X summaries is a different character. Newer mappings push her deeper into 4.X, so do not expect Anna's splash art to look anything like that.
Lucille in WuWa 4.0: Names, Design and Kit Rumors
Lucille is thinner on detail than Anna. There is no art, no weapon and no confirmed spelling of her name, so what follows is the short list of things the leaks actually claim, in order of how useful they are.
?
The "Cowgirl Catgirl" Description Explained
Her earliest tag translates as an affectionate catgirl, and a later, more detailed version of the leak adds a cowboy or Western styling. That is a costume direction, not a region, and it suits a nation whose lore already runs on frontier settlements and mercenary crews.
Affectionate is a personality cue, not a kit hint. It points to a warmer character who can show the civilian side of the Federation while Anna works the political angle, roughly how Kuro split Lynae and Mornye across the Lahai-Roi opening.
No official art yet, so hair colour, outfit, faction markings and feline features are all still up for grabs. The fan art already circulating under her name is speculation, however good it looks.
Lucille's Rumored Attribute, Weapon, and Sub-DPS Role
A sub-DPS in WuWa usually means short field time, coordinated attacks, Outro Skill amplification, or damage that keeps ticking after you swap out. If the Hsin and Suoming link holds, Lucille is far likelier to speed that rotation up than to take Hsin's on-field slot.
Lucille, Luciel, or Luxier?
The Phase 2 character turns up under three English spellings. Lucille dominates community posts, while other translations give Luciel or Luxier. Luxier is the handiest of the three, because it does not collide with Lucilla, the Glacio Rectifier Resonator already in the game.
Lucille and Lucilla are separate characters, and mixing them up is easily the most common slip in 4.0 threads right now. The official spelling comes with her English profile, so until then it is worth searching both.
WuWa 4.0 Reruns: What's Rumored and Who Players Want
Rerun info is always the last thing to firm up, and the WuWa 4.0 reruns are no exception. The only name circulating for Phase 1 is Qingxiao, the Aero Sword main DPS from Version 3.6, which would be her first rerun.
The Most Plausible WuWa 4.0 Rerun Candidates
With no official rerun list to work with, the useful move is to look at which Resonators keep showing up in rerun requests and what gap each one actually fills on an account.
Build your rerun budget around the role your account is missing, not around how old a character is. Shorekeeper is the one rerun that lifts almost any roster; the rest only pay off if you are already invested in their Attribute or archetype.
Could a Second Starpath Reverbs Banner Return?
The format matters more than the names here, and Kuro has already run the generous version of it once. Starpath Reverbs went live through Version 3.5, from July 10 to August 19, 2026, let you pick one of six older five-stars outright, and threw in a free ten-pull on top.
That rerun pool was strictly 1.X: Jiyan, Yinlin, Jinhsi, Changli, Zhezhi and Xiangli Yao. A major version full of returning players is exactly where a second round fits, and a 2.X pool would be the obvious next step.
One thing to keep in mind before you budget for it. Reverb Resonator Convene banners run their own guarantee count, shared only with other Reverb events, so pulling there does nothing for your Anna or Lucille pity.
Wuthering Waves 4.0 New Region, Map, and Combat Mechanic
So far this has all been about who shows up. The region itself matters just as much: its traversal system, its Echoes and its combat mechanic decide how long Anna and Lucille stay useful, which is the part worth reading before you spend Astrite.
What the New Federation Already Is in WuWa Lore
New Federation is not a new name at all. It is an established WuWa nation on Solaris-3, openly cyberpunk, and the game has been feeding us details for over two years through the Resonators who come from there.
It is a country built on technology worship, where spotting research talent can redirect someone's entire life. It runs an annual science exposition, and Lucilla edited its top academic journal before she took over Startorch Academy.
The social structure is what matters for the story. There is an aristocracy that Mortefi was born into, and at the bottom sit the Exiles, shut out of legitimate work and pushed into camps on the outskirts known as the Lawless Zone.
That zone is where Calcharo built the Ghost Hounds, and once the central government finished its campaign against the gangs, it turned into a mercenary pool for the upper class. Aalto, Encore, Lynae, Mornye and Verina all trace back to the same nation.
Federated Cities is the term players keep bumping into, and it comes straight from Lily's official profile and its Resonator War. Lily worked there as a perfumer and psychotherapist during the fighting, which is the clearest hint yet that 4.0 opens on a country still paying for a war.
What Could the Wuthering Waves 4.0 Map Look Like?
Every Wuthering Waves 4.0 map leak so far points the same way: dense urban districts, heavy industry, elevated transit, and rougher ground outside the main city. That tracks with a nation whose lore name-drops planes, corporate finance and a capital tied to company power.
New Federation is the nation, and 4.0 will almost certainly open just one slice of it. Jinzhou covers a corner of Huanglong and Ragunna covers a corner of Rinascita, so later 4.X patches have plenty of room for industrial zones and Lawless Zone territory.
A layered city also explains all the interest in air travel. Rooftops, industrial towers and separated street levels give a flying vehicle a real job instead of leaving it as a novelty.
Will Wuthering Waves 4.0 Add a Flying Vehicle?
Data mining has turned up a new vehicle entity for Version 4.0, labelled in the files as Anna's flying car. Players have run with that as proof of a flying car, though strictly speaking the entry only shows that something vehicle-shaped exists.
The pattern behind it is solid, though. Version 2.0 gave Rinascita a full flight module with its own stamina bar, and Version 3.0 gave Lahai-Roi the Expedition Motorbike with boosts, grappling and route autopilot. Every region gets its own way of moving.
The open question is how freely you will actually get to use it. A summonable exploration tool, a story-only vehicle, and a fixed transit network are all on the table, and they feel completely different day to day.
The Rumored Wuthering Waves 4.0 Combat Mechanic
Leaks also describe a combat change big enough that people are calling it a new version of Tune Break, not a separate system bolted on beside it. If that holds, 4.0 would be the first real revision since Version 3.0 introduced the thing.
Quick refresher if you skipped Lahai-Roi. Your attacks build Off-Tune on an enemy until they hit the Mistuned state, and that is when your active Resonator can fire a Tune Break Skill: damage, an interrupt, and the gauge resets.
On top of that, certain Resonators apply Shifting Effects. Break a Mistuned enemy carrying one and they drop into the Interfered state, which powers the two branches we have now: Tune Rupture for coordinated follow-up attacks and Tune Strain for damage that scales with how many teammates share the effect.
A third branch, or a rework of those two, is the most likely shape for WuWa 4.0. Anna would introduce it as the opening character and Lucille would stretch it further with off-field damage or a swap effect, which is exactly what Qingxiao and Mornye did for Tune Strain.
For older accounts the real question is access. A universal layer hands your existing Resonators new rotations; a branch locked to New Federation characters makes Anna and Lucille much harder to skip.
Will Version 4.0 Add New Echoes and Sonata Effects?
Every major region in WuWa so far has brought new Tacet Discords, Echoes and Sonata Effects, and Version 3.0 is the template. It shipped Halo of Starry Radiance and Pact of Neonlight Leap specifically to feed Off-Tune scaling.
Expect the same if the mechanic really is changing. Until the beta shows whether those sets lean on ATK, Energy Regen, coordinated attacks or Tune Break damage, holding your premium Tuners is the cheapest call on this whole list.
WuWa Upcoming Characters: The Wider 4.X Roster
The 4.X roadmap runs well past Anna and Lucille, and this is where most of the WuWa upcoming characters discussion currently sits. Almost none of them have confirmed names, but as a group they sketch a cast built on military, corporate and urban-fantasy themes, which is a decent preview of what future WuWa banners will look like.
The SP rumors are the most credible entries on that list. Verina and Calcharo both come from the New Federation, so an alternate form during its arc would follow the same logic Kuro used when Yangyang got the first SP treatment in Version 3.5.
How Solid Is Each WuWa 4.0 Leak?
That is a lot of leaked material in one place, and banner predictions age badly. So before you act on any of it, here is everything above sorted by evidence level.
Should You Save for the WuWa 4.0 Banners?
It is too early to build a firm plan, and anyone handing you a confident verdict right now is guessing. Neither 4.0 character has an Attribute, a weapon or a kit, so the useful goal is a budget that survives whatever the beta turns up.
How to Prioritise Anna and Lucille
Anna is the safer default if you only have room for one. Opening characters are usually built around the region's new mechanic, and that tends to keep them relevant long after a mid-version release has been power-crept.
Lucille only matters if you already run Hsin and Suoming. Her rumored Fusion sub-DPS role points at finishing that rotation rather than starting something new, so without the core she is an easy skip.
Nothing here is worth locking in before drip marketing lands in late November. Hold the Astrite, keep the option open, and let the beta make the decision for you.
A Practical Astrite Plan for Wuthering Waves Version 4.0
One Convene costs 160 Astrite, spent as Radiant Tide on characters and Forging Tide on limited weapons. From zero pity, 12,800 buys you 80 pulls and one guaranteed five-star. Lose the 50/50, though, and a featured character stretches to 160 pulls, or 25,600.
The number most players should aim for is one full guarantee on top of whatever pity they are already carrying. That protects the character you actually care about without needing an early five-star or a 50/50 win. Chasing both 4.0 banners means either a much bigger reserve or a clear favourite.
Final Thoughts
Anna is the strongest lead for the opening WuWa 4.0 banner and Lucille is the likeliest Phase 2 pick, but neither has an Attribute, a weapon or a kit yet. What you can plan around is the shape of the version: a new region, a reworked Tune Break layer, and the characters built to use it first.
Set aside one full guarantee, let Version 3.8 play out, then use the 4.0 beta to decide whether Anna's mechanic, Lucille's team fit, or a rerun you have been waiting on matters more to your account. That keeps you flexible without forcing you to skip a 3.8 character you actually want.
Wuthering Waves 4.0 Banner FAQ
Does Pity Carry Over from the 3.8 Banners to the 4.0 Banners?
Yes. The guarantee count on the Featured Resonator Convene is shared across those banners and carries over until you land a five-star Resonator, so a lost 50/50 in 3.8 still protects you in 4.0. Character and weapon banners keep separate counts. Kuro publishes the full rules for every banner on its official Convene rules page.
Should I Skip Lily to Save for Anna?
Only if your healer slot is already covered. Lily is confirmed and Anna is not, so dropping a known quantity for a character with no Attribute yet is a real gamble. If you own Hsin and Suoming, Lily is the safer home for those pulls.
Would a New Starpath Reverbs Banner Share Pity with the 4.0 Character Banners?
No. Reverb Resonator Convene banners run their own guarantee count, shared only with other Reverb events. Pulling a selector gets you no closer to Anna, so budget the two separately if both show up in Version 4.0.
Will the New WuWa 4.0 Combat Mechanic Work with My Current Resonators?
Partly, if Version 3.0 is anything to go by. Off-Tune and Tune Break were handed to the whole roster, while the stronger responses stayed on new Resonators. A 4.0 revision will most likely split the same way.
Are Verina SP or Calcharo SP Coming in the WuWa 4.0 Banners?
Not in the opening banners. Both names sit in wider 4.X chatter, and the leaks openly contradict each other on whether they are still in development. Neither is worth reserving Astrite for right now.
Will Wuthering Waves 4.0 Add a New Four-Star Resonator?
Nothing in the current roadmap points to one. That earlier unnamed four-star male rumor was attached to Version 3.8, not 4.0. Four-star rate-ups usually land with the official banner reveal in the Special Broadcast.
When Is the Next WuWa Banner After Version 4.0?
Version 4.1 would land around early February 2027 on the 42-day cycle. Leaks put Amethyst and a nano-tech male Resonator there, so if neither 4.0 character grabs you, that is the next realistic target for your Astrite.
How Much Astrite Should I Have Before Version 4.0 Starts?
25,600 covers one guaranteed featured character from zero pity. Add roughly 12,800 more if you want the signature weapon too, and double the character figure if you plan to pull both Anna and Lucille without picking a favourite.
