LittleBigPlanet vs. Fable 2, Resistance 2 vs. Gears of War 2

[FaRmLaNd]

None of these games are out. So you cannot say which one will be the best.

That said, gears will easily sell the most out of the list.

R2 should beat fable 2 handily but I'm not even going to guess LBP. Its just too much of a wild-card.
