I've said this thousands of times to my mates and on other forums, graphics polish off a game and make it look nice, but they DO NOT make the game!!
You can have the best graphics in the universe and still have terrible gameplay which makes the game crap overall, and you can also have terrible graphics but brilliant gameplay which make it a great game (the original GTA for example).
From those vids it doesn't look as great as you make it out to be. Still very good, dont get me wrong! And looks like it will be a good game when it comes out, but I think your overhyping it.
Doesn't look anywhere near as good as Crysis when running at very high settings IMO.
