I admit that I am keeping an eye on Guild Wars 2, even though I don't like the first game.
I don't put too much stock in the developers' hype - we've heard this sort of thing before about MMOs - but I'm interested to see how it turns out.

Forgot about Shogun 2 and Arcania, those two should be pretty good as well. I'm not a big MMO fan, but I'm keeping an eye on Guild Wars 2 as well... maybe I'll be pleasantly surprised.

Well, their one other game was amazing, selling 6 million+ copies and most of what they said about that was true.
Guild Wars 2 looks amazing from what was shown so far, and the book, Ghosts of Ascalon, has a very good story that I hope is continued in the game.

I wouldn't say 'excited' for all of them but, to varying degrees, I'm looking forward to:
Civ 5, Fallout New Vegas, Torchlight 2, Trine 2, Brink, Deathspank for PC (which will probably never come), and er... one or two others whose names escape me right now. Note that I have no plans to pay full retail price for anything except possibly Torchlight 2 and Deathspank assuming they have 'budget' prices.
