I've found out some of the controls for this game. ^_^
These controls are for the PS3 version

L2 - Accelerate
R2 - Drift (it has drift!) :D
R1 + L1 - Tricks ( apparently, using the 6axis motion, you will be able to shake the PS3 controller for a triack) :D
X - fire an item
Square - look back

source: Sonic & SEGA All-Stars Racing - =SSMB=

it also has stuff about items and character special moves in that link

I removed the second Knuckles.

NIGHTS will be in the game.
I just want to add the confirmed characters.

I think this looks great! I'm somewhat a fan of cartoon-ish racing games
I think I'll get it, but I'm not going to pre-order or anything. And I'm sure NiGHTS will be in to whoever mentioned him

lol alex kidd

Sega's released a lot of fail games these past few years.... except Superstar Tennis! I look forward to this!

New character! Ryo Hazuki

Ahhhhh....Online,im pre-ordering. This game will be beast,but no silver,but Shadow,my second fav~

I'm happy they used the classic characters.
More should be coming, but not from the Sonic world.
