We're just making predictions...they're all huge games from big developers...and we've seen a lot of Mario, the Halo multiplayer beta, and ...a couple trailers for GTA? So we know a bit about each game to make predictions.
I am worried about GTA's current state though...it sounds like it needed a lot of work after its closed-door preview...
And PS3owner, Wii Sports won game of the year on a TON of sites...so I don't think graphics are going to hold back Mario from winning awards...it looks great anyway.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
