Yes, i've said few times that Porting SF4 for the Wii would be easy. Those graphics look nice, but they also can be done on the Nintendo console.
And fighting games do work on the Wii, they need to enable GC controller and Classic controller. Also create a control scheme which uses nunchuk plus remote.
Brawl does it great and also Dragon Ball Budokai Tenkaichi 3 (which is my favourite fighting game since Tekken 5, performing kamehameha just like Goku did is awesome)
