Street Fighter IV is 2d and then?

Though the screenshot doesn't answer this question outright, we can confirm that the game's graphics are polygonal but the gameplay is strictly 2D. There will be new moves, locations, and gameplay features, while the standard six button control scheme remains. Ryu and Ken return along with Chun-Li and Dhalsim, but beyond that the character roster is a mystery. And then there's the issue of what platform(s) the game will end up on, which at this point Capcom is keeping close to its chest (if you search 1UP's database, you'll find listings for arcade, PlayStation 3 and Xbox 360 versions, but those are just guesses based on the graphical quality).

Ok, this time they still make it to be 2D, but see from the ss it looks like 3D. I am afraid 3D maybe a trend although many people and me still like 2d gameplay mode and do not want it to be 3d. However, korean has already made out something looks like 3D Street Fighter.

Check: HERE. the video looks a lil weird but more 3D than SF EX.
