Retro Studios assisting with Mario Kart 3DS

During the annual Nintendo developer roundtable, Shigeru Miyamoto casually let it drop that Metroid Prime/Donkey Kong Country Returns developer Retro Studio is helping Nintendo out with the 3DS Mario Kart game -- which, incidentally, runs at 60 frames per second.

According to Miyamoto, Retro is collaborating on tracks, among other things. And then he joked that he wanted to call it "Super Mario Kite" because of the gliding vehicles.
