Mario Kart never really blows anyone away though does it?
Hopefully that lack of graphical push allows sweet 3D effects, with twelve player online races to boot. Mario Kart normally pushes the system's online capabilities, and this should be no exception. It isn't about the graphics with a game like that, and a Mario Kart trailer is always going to look relatively similar to the one that came before it. Just hope that the gameplay is as special as the series is renowned for.
Some of those games look interesting. There's one by Konami that looked like Professor Layton, but was all in Japanese, and a few RPG games that looked fun.
