Don't they also help with Mario Kart, as well?
Also, if they are helping maker a MM like sequel that can be out sooner, I hope that they at least slightly tweak the art style. MM was definitely darker looking than OoT, and I appreciate every 3d Zelda looking a little different from any other.
That was Retro Studios, I think.
