It looks like two more characters are entering the fray. No stranger to the Marvel vs Capcom franchise, Akuma will be an unlockable player at 2000 Player Points (which is said to be about a single play through of the Arcade mode). Newcomer Taskmaster will also be an unlockable player at 8000 Player Points. Taskmaster is a Marvel comics character that has the ability to duplicate the fighting style of anyone he has ever watched or fought.

Supposedly there are still two more characters we have not seen yet. Feel free to speculate in the comments!
