They’re only datamined announcers for potential inclusion of the next seasons. Some are still too important like other RWBY & Arcana Heart cast mostly.
Unless based on my calculations, one of them who are sprite clones, guest fighters, & characters other forms within same universe/timeline should be remained excluded. Cause this ain’t main game series like GGXXAC+R; BBCS - BBCF & DBFZ, neither Capcom crossover games (SNK (CvS - SvCC) nor Marvel (MSHvSF - MvC1)) games:
Tsubaki Yayoi (Base): Already have her Izayoi form playable
Lambda & Noel Vermillion (Mu): Two Nu’s Sprite clones. The latter’s case already have her Base form playable
Yuki Terumi (Base): Hazama’s sprite clone. Which means only his Susano’o form still have a chance
Shadow Labrys (Asterius): Sprite clone of the original. X( Duh!
Sion Eltnum Atlasia: Guest fighter. Unless Melty Blood announced as 8th fate
SHO & MINAZUKI: Given how Persona Episode alternatively took place after P4AU, there’s only 1 Sho Minazuki, simply as “Sho”. A hybrid between SHO & MINAZUKI from P4AU True ED
Given how Jin & Hakumen are safe because the latter being the former’s AU/AT counterpart. There are few safe bets through special cases I can tell which one aside Sho:
Saki Tsuzura: Since she’s a semi-shotoclone of Heart, ArcSys & Examu may likely find the way to to make Saki completely differentiate from Heart in BBTAG than in home series to avoid same sprite animation (mostly normals)
Akatsuki: He should return to his home titular series section since he’s the OR hero there, & guest in UNI
Since the game will be crossover, I think the control schemes & the functions will be different from some of the previous ArcSys titles, especially may affect the characters from different series on the movesets, & sprites, like from P4AU & UNIST mostly.
There is no "good" and "evil" halves of Saya. There is one part in Noel, one part in Izanami, one part in the Origin. Izanami's part is not "evil", Izanami herself is evil and wants to destroy everything, since she is the opposite of Saya's power to create. Now STOP, or I'll lock the pages.
I've said it time, and time again. Please, no speculation. I'm happy that you edited to let others know that Mai and Cajun would be appearing in CPEX, but there are no sources anywhere (as of 20/01/2015) that say that they are both playable.
I wasn't shitting about when I said it last time. When you can, reply to this message to let me know you can get on the Wiki Chat. If you make an edit after this message and don't reply? Then I will be pretty cross.
(I'm sorry if this at all sounds rude). Nearly every edit you have made in the last few days has either been speculation or opinion. Bloodedge being considered the true Sixth Hero isn't mentioned inside BB Canon and is your own opinion. Relius' colour palate is based on Liz, just because his seyuu is somehow related to Teddy's doesn't mean that he is immediately based off of him.
I'd also like to point out that Bloodedge isn't Ragna's future self because Ragna in the current timeline is already far past the event that would send him into the past and make him Bloodedge.
