It's a definite must buy for me but for some reason it's not a day 1 purchase. I'm getting through Uncharted 3 and loving it sooooo much, then once that's finished I have Shadow of the Colossus HD to tackle (I finished ICO before starting Uncharted 3), once I get those over me then I can think about Skyrim so might well be getting near Christmas before I get it.
I'm also waiting for a few reviews to see if there is any discernable difference between PS triple and 360 versions. My preference is probably for PS3 because it's on the big 42" telly in the lounge as opposed to the 23" set upstairs so the scenery will look even more stunning, but we'll wait and see what the reviews say.
If I had a signature, it would go here
