Definitely Skyrim for me as well. I actually can't think of any games other than Skyrim I really am excited about, except perhaps Fallout 4 which probably isn't coming out for a pretty long time.
Mechwarrior Online, and that's about it right now. I won't be excited about Skyrim until I can confirm I'm going to like it. After being disappointed in Oblivion I'm keeping my expectations low.
Armored Core V Is The Game I Am Looking Forward Too Next Even Though There Is No Confirmed Release Date As Far As I know. I Already Have The Two Games I Was Looking Forward To This Season, Battlefield 3 And Forza 4
I'm most excited for Skyrim, but there are others games that I'm really anticipating the release of. Such as WWE 12, Assassin's Creed Revelations, GTA 5 and Mass Effect 3
