Like I said, I think a lot of this will be movie decided, but if the leaks are to be beleived, we might get some characters that haven't even been animated yet (Gwenpool, Ms. marvel, etc), those were proven fake but Ms. Marvel would be a great decision
Jesus was it that Early in development? Maybe they could get Jack in there between then and now, especially since communication between Marvel and Capcom won't take weeks like last time.
As for capcom reps I want...
Asura, Edward Falcon, Leon S Kennedy, Jack Baker, Lost Planet rep, Monster Hunter rep... idk why not Dragon's Dogma too
Marvel reps:
Ms Marvel, Red Hulk, Carnage, Ultron, Silver Surfer and. Fuck. I dunno Blade
