Looks stunning. I think they've done a great job of balancing the realistic and fantasy themes, both technically and artistically (though in these shots there's more of the former than latter)
I feel the need to mention though that i'm not entirely certain these screens are 1080p. Doesn't mean the final game won't be, and it could just be the strong DoF messing with my eyes, but it looks more like 900p. Obviously won't stop me buying and enjoying the game, but i thought i'd mention it ^^
