Okay, I'm going to have to LOL at all the Ninty fanboys who voted for SSBB twice as often as GTA IV.
SSBB will do well, but it's still only on one console. GTA IV will move a lot of units for two separate consoles, at least one of which will almost assuredly get a price drop right before the game drops. SSBM sold well but it wasn't an Earth-shattering game while every GTA installment since III has sold like crazy.
And for those of you touting the attach rate on SSBM to explain your vote, remember a few things... The bigger an install base gets, the more diverse its userbase becomes and attach rates drop. The GTA series had an extremely impressive attach rate despite the monstrous size of the PS2 userbase. Also, comparing the "Nintendo hardcore" demographic on the GC to the wildly diverse Wii demographic is comical at best, completely retarded at worst.
