Street Fighter 4 could pull a Soul Calibur 2... 3 versions with exclusive characters in each... That could be lame, though, too...
The reason PS3/360 but not Wii is likely is because it may be first and foremost an arcade game... PS3 and 360 versions would be ports, but a Wii version could really be a drastic downport... But if it's primarily a console game, there's no reason they couldn't do concurrent development of both a PS3/360 and Wii version... It's a question of how they approach development, but I'm not holding my breath for a Wii version, honestly...

"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
