Mr. Sakurai discussing the possibility of adding a Capcom character or two to the mix. Prolly would be Ryu or Mega Man.(Makes the most sense to me anyways)

Megaman X is probably the best character. He fits in the game still and can take advantage of the Hadouken and Shoryuken, the most iconic moves in a fighting game.
