Well according to NPD:
Luigi's Manion: Dark Moon is overtracked by 92K so it should be 1.39m.
Gears of War: Judgment is undertracked by 18K so it should be 1.15m.
God of War: Ascension is undertracked by 49K so it should be 1.09m.
These 3 games will undoubtedly remain in the top 10 bestelling exclusives this year. By the end if this year I'd predict the bestselling order among them will be: GoW:A at ~2.50m > LM:DM at ~2.25m > GeoW:J at ~1.75m. (I'm predicting big bundling this holiday for GoW:A, not sure about LM:DM, doubt it for GeoWJ).
If GT6 does release on PS3 this year that'll be either the 1st or 2nd biggest exclusive, the new handheld Pokemon game will be huge, I think TLoU will be big, Beyond Two Souls will do decently, Zelda remake for the Wii U will do well and a new 3D Mario game will do very well. Not really sure what else will do well, I must be forgetting something.
