I still play SSX3 all the time, so I am pumped for this. Will get it if fellow XBLers are, otherwise I'll buy it cheap in summer.

The rewind looks pretty interesting. Obviously, it'd be ridiculous to have it in races and such, but I think it has a decent application in single player dick-abouts. And the map exclusive "gimmicks" looks smurfing awesome; definitely seem to add something to the experience and make each map something other than "snow in different directions".

EDIT: Agree with DM, though. If it doesn't have local multiplayer then it's a no-buy. Game still looks fairly ridiculous, if not as colourful which is a shame.
