Bioshock: Infinite
The Last Guardian, assuming it actually does get released this year.
Journey
Quantum Conundrum
Papo & Yo
Honorable mentions also go to Far Cry 3, Prey 2, Metro: Last Light (even though I wasn't able to play the first one), Dishonored, and South Park: The Game, since they all actually look kind of interesting, but I'll need to see more before I'm truly sold on them.
