A portion of a Kartel interview with producers Omar Woodley and Dan Gallardo…
K: Was Mario ever considered a possibility as a special character for the Wii version? I mean he’s got his own Kart and everything!
O: Everything is a possibility. It definitely was discussed way early on in development, but just the fact that we have the whole separate “Mario and Sonic” series; well frankly we didn’t want to cross contaminate them.
K: Is it true however that the Wii will not get DLC because of memory issues?
O: Yes, DLC will just be for the Xbox 360 and PS3.
