Okay, this is a little late, but I've got a bunch of info

She Hulk (YAY Hawk Girl VA) and Zero (Yay Ichigo VA) confirmed

Also some full gameplay matches. Zero looks BRUTAL

And on top of that the Collector's Edition have been announced. It's have fancy packaging, and collectibles added. But it also have vouchers for the first two DLC characters, Jill and Shuma Gorath.

On top of that it looks like we've got a solid idea on the nearly complete roster thanks to an inside source. Yes, yes, I know a lot of these "leaks" are made for lulz and trolling, but this seems to be a high chance to be real. A couple weeks ago someone claimed to have an inside source knowing the complete roster. And that Jill and Shuma would be DLC characters. And well, fast forward to now, and he was spot on with Jill and Shuma being DLC! His roster was as such, i've spoiled it in case anyone hates finding out about game info ahead of time:

And this leaker also shared a few details on the yet-to-be-revealed characters

"Phoenix is like Gill from SF3, when her Super Gauge is full when Ko'd she'll revive as Dark Phoenix"


Taskmaster info:
- He can shoot his arrows straight upwards, and can fall down, think Magikina Mina of Samurai Spirits fame.
- He uses his shield to do reversals like Gouken.
- TM is sorta like Seth in that he has variations of other characters' moves as normals such as Spidey's webswing and Captain America's charging star.


Mike Haggar
- Shares some of Zangief's moves but only to an extent as he is still very much his own character
- HP has him using a lead pipe
- Super 1 - Punches with one arm over and over again, think Cracker Jack in SFEX
- Level 3 Super - Final Haggar Buster (his version of FAB), ends with piledriver which results in different camera angles on the last frame, think when you beat someone with a super in Star Gladiator

C. Viper
- She has EX moves that take metre, done by using the Exchange button to do the moves
- She has a Focus Attack, which may have potential for assist traps

Note this leaker has said it's entirely possible that their source didn;t know this roster as the complete roster. There could still be more reveals.

Another fairly reliable "inside" guy named Henaki has said the Eepisode 3 trailer will feature "Lei-Lei (Hsien-Ko) and Strider Hiryuu teaming up to fight a silver hooded friend of Deadpool (Taskmaster)"

So as far a rumored and leak lists go, THESE are the ones to bet on. Time will tell.
