Why isn't Duke Nukem Forever on this list?!
Also, does The Last Guardian even qualify as a sequel? I was under the impression a sequel was the continuation of a story - and I was also under the impression that The Last Guardian had nothing to do with either Ico or SotC. Although, really, I could be completely wrong about that last part. I haven't been keeping up with The Last Guardian at all.
Anyways, I'm most looking forward to Bioshock Infinite - out of that list - because I think it'll probably be the one that I like the most.
Skyrim sounds great, from what I've read, but since I've not seen or played the real game I can't say that I think it'll all work out.
Arkham City is another one I'm looking out for - because, y'know, that other game they did was pretty good. Or at least, I heard it was. I think.
I've been purposely avoiding Portal 2 because I want it all to be a surprise when I play it. By the way, I will be very pleasantly surprised if it comes out this year. I have a hunch it will be delayed again.
