Don't forget that there is a possibility that Star Wars: The Old Republic will turn out to be a better WoW-style MMORPG than WoW, which might make it GOTY (Depends on how tired ppl are of WoW-style MMORPGS, even if this one turns out to be the best of them all).
Either way, my vote is for The Elder Scrolls V: Skyrim. So far, it's gotten better reviews than all the other ones.
I also like the fact that, on average, Uncharted 3 scored higher than either MW3 and BF3, in light of all the hype that was going around about them (The same might also be said of Batman: Arkham City).
