I consulted with Mr.Megaman(his name is Mr.I…) about it 1 years ago.Its result! ;D
Mr. I eh? A reference to Keiji Inafune, Mega Man’s creator? Might he have had input on the game even after he left Capcom?
Ono also went on to talk about why there are so many guest characters in the first place. He assured us that these guest characters aren’t “using up character space.” He said that the Street Fighter and Tekken Characters are using up the actual space in the roster and every other guest character was made on top of that.
He finished by saying that more normal Street Fighter X Tekken characters will be revealed soon.
