I agree, waggle controls have no real place in any 2D, 2.5D or maybe even a quasi 3D fighter (unless done really well). For a 1st person fighter (like Wii Sports Boxing) they could be great but not for Street Fighter.
The only motion control that might feel good in SF could be Ryu's fireball but it would probably simplify the game too much to map special moves to a motion. So I still think no, unless maybe they made a Wii specific game. For SF4 it would have to have Classic/NGC controller support though.
Everything in this signature except for this text was made by Wiired, he is my creator and almighty.
I wonder what the specs needed for the PC version are ?
To put it another way
If I can get it running on any of these PCs ive got this X arcade stick will be plugged into that PC
Nintendo realizes (hopefully) that they will need to change their controllers again. I know Nintendo changes their controllers from time to time, but they can't expect to keep using motion control as some games just don't work on Wii. Why limit Wii owners, make something that is accessible.
