And it wouldn't be that unusual for Mario to be in the game. Sonic & All-Stars had other guest characters: Banjo-Kazooiee from Rare, Wreck-It Ralph from Disney, Danica Patrick from Nascar, the Avatar from Microsoft, and the Mii from Nintendo. Mario can fit in perfectly fine. And he has his own kart from the Mario Kart series which can transform for water and air sections in Mario Kart 7. SEGA could just call his vehicle the Mario Kart as a homage to his kart-racing series.
