i really dont count anything that came after ss4 as a real 2d SS. so hell yeah, only if they truly made a new game that would live up to the expectations of what we had when SS2 got released.
so if theres new cool (not gay like andrew and all the new ones except yohitora) charas, cool old returning charas (roster should be at least 30), hella better graphics and animation than sf3ts, music and sound to match the Graphics, gameplay as fast and great as sf3ts and balancing like in the best vs fighter, then hell yeah. otherwise if they want another tenkaichi they can shove it up ther ass.
