Yoshinori Ono, a producer at Capcom has gone on record and said Street Fighter IV could possibly head to the Wii. He feels the game could work on any platform, since it's the controls that are important, rather than graphical details.
"Street Fighter IV, as it stands now, would be well suited for the higher level platforms. But the game doesn't need these visuals in order to be fun. We could go, potentially, to the Wii. We could make it on Game Boy for all we know right now".
"As long as the rules are the same, that can be independent of the visuals. So we're not going to be limited by any hardware specs; we're going to aim as wide as possible".
Of course, this is no confirmation by any means, and could just be lip service.
