IS THAT LINK IN A KART????

[Kriven]

Considering that Sega already has it's own version of Mario Kart starring the Blue Blur, that's pushing it a little.

Mario was actually intended to be a guest racer in the Wii version of Sonic & Sega All-Stars Racing, but was cut because Sega "didn't want to cause confusion with the Olympics Games franchise."

So I'd say Sonic being in Mario Kart isn't too out there.
