That's an understatement... we'll be lucky to see a new Smash game within the next 10 years at the rate Nintendo is going with updating their franchises.  I would love to see a DS version that looks/plays akin to the original N64 version, which is still my fav from a gameplay perspective.

Besides that, the only think that would interest me in another Smash game at this point is if it went almost completely third party and Nintendo managed to get about a dozen or so third parties on board with their major characters, cuz otherwise it'll just basically be Melee v3.0.

Brawl for me is the most overrated game I've ever played, even moreso than GTAIV IMO.   Was just a huge dissapointment for me and totally not worth the 7 year wait.

I'd like to see a chemical blox from boom blox as an item.

I would so want to see Travis Touchdown in there, he's a perfect fit. Also, I know it ain't going to happen but Jack from MadWorld..???
