A new developer column was posted today! It has information about the "P5Fes" event and upcoming versions:
First off, they mention that they're planning to do developer columns more frequently in the future!
"The P5Fes Teaser PV, the official Version PV, and new "Phantom Thief Impressions" will be officially released very soon"- I'm not sure if this means we'll get the trailers for this event/version sooner than usual? Normally, I'd expect to get them in about a week, over the weekend prior to the update
About WonderWorld:
"Serving as the central stage and defining feature of the P5Fes version, "Wonder World" is a unique spatial-temporal zone steeped in an air of mystery. Within this realm, a dedicated host awaits to welcome each and every Leader upon their arrival.
Here, you will encounter a diverse cast of "Interlocutors," each possessing a distinct style and personality. Each Interlocutor features their own exclusive storyline and unique Bond interactions, allowing you to unlock their individual narratives and immerse yourself in the unique charm of every character.
Furthermore, "Wonder World" will simultaneously introduce a brand-new Co-op Battle mode. This feature allows Captains to team up with other players to take on powerful Bosses together. Not only will you get to experience the thrill of fighting side-by-side with allies, but you will also earn generous rewards—unlocking a whole new dimension of multiplayer combat!"
They hinted at Version 5.1.1's banner character, who appears to be a dancing alt of Joker, described as "5★ Limited Phantom Thief | Curse | Virtuoso | Leadership Power":
As well as v5.1.2's banner character, a dancing alt of Morgana described as "5★ Limited Phantom Thief | Wind | Saboteur| Form Transformation":
In v5.1.1, it sounds like they're bringing over Crow's buff from Global, as well as buffing Aigis in response to player feedback
Yukari and Frostgale Mont's Core Activation Mindscape nodes will be unlocked in v5.1.1
Aigis' banner will be extended for one week into v5.1.1, and there will also be rerun banners for Yukari and Frostgale Mont
They hint at another Wind teammate being added later this year after the dancing Morgana alt, as well as a new Wind element-focused Wonder knife
There will be another preview stream (where they showcase future game versions) prior to the end of v5.1.2
