I've just received word over Twitter that there was a mention of Super Street Fighter 4 during the CAPCOM slide for the Nintendo 3DS reveal. Wes Phillips, Capcom PR, also confirmed "Street Fighter" is coming to the DS. Nintendo's Press Site also lists a Super Street Fighter 4 3D Edition (name not final) as a third party title for the system. It's coming folks.
Considering Street Fighter 4 was developed for the iPhone, this isn't a huge shock that CAPCOM is making a 3DS port of the game, but the big question is: how will it control? Will it be a somewhat classic control interface or some interaction with the stylus? Will there be 3D elements in game -- perhaps 3D Ultras -- or just a lo-res version of what is already on 360/PS3?
We'll update this post if any new information pops up in the following days!
