Sifer2 got the point. We all hear is how PC version spectacular look and work so far...but all we got is 40 seconds of 3D scene. So I say there will be no huge difference with dx11. It's all marketing...remember crysis "exclusive" dx10 features? Screen resolution is a different topic and yes it will make pc version look better in any way. I really hope for PC trailer, but i guess it won't be any, because in action you couldn't say if its a pc or consoles graphics.
