The good folks at Siliconera recently spoke with Leo Tan of Capcom Europe about Street Fighter IV
, and while they left out the DS when asking specifically about other systems that might be possible for the game, the answer was interesting (even though we've heard it before): "I do realize that earlier in the campaign we talked about putting it on every platform imaginable, including GBA if there was a demand. Whilst a GBA version seems unlikely, the fighting system itself (not the graphics, obviously) could easily transfer to any system with six buttons and a dpad so nothing should be ruled out. Ever. If people shout loudly enough that they want something, they often get heard."
Well, the DS has a D-pad (even if it's small!) and six buttons, so that puts it into the realm of possibility. But would you want a visually-stripped version of Street Fighter IV
for the DS?
