Left 4 Dead (or Left 4 Awesome)
Little Big Planet
Spore
L4D is pretty understandable why, you run around killing zombies with 4 player co-op, how can that not be huge, especially when it is made by Valve and sold on Steam, if it leaves the top 3 of Steam's best seller list for the rest of the year I would be suprised.
LBP is just so fun looking that I don't see how people can not pick it up, hell people still buy remakes of the first four mario games on gba and ds.
Spore, this game should be huge, like 10+ million huge. Especially considering all the versions coming out. Slap on "From the creators of The Sims" and it will sell for a long long long time and have probably 5 expansions (hopefully one of them will allow me to keep my guy underwater and have an underwater city and what not).
