Maybe I'm cheating a little but Persona 4: Golden was released in Europe this year and the amount of new stuff they added in that game is just insane. Same goes for all the little UI, combat and social link fixes they did.
So, yeah, P4:G is my GoTY so far. Second is BioShock and third is either The Last of Us or Persona 4: Arena.
Really surprised that they chose a Garbage song for their trailer, not that I'm complaining, Garbage is a fantastic band. Pretty darn great trailer, too. Makes me really excited to see what the final game will be.
