As for details on the platform the game will be appearing on? Well this is still a mystery. As for the games graphics it has been revealed that they 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 know other characters have been revealed.
Look out for the January issue of EGM for more info.
