Personally im not all that impressed. Doesn't look all that better than say CoD4. It may do stuff technically better but the differences on screen aren't all that (aspecially considering since CoD4 is 60fps).
Nice animations and all that, but that particular video didn't really wow me.
Oh well opinions and all that. I guess if you're sensitive to frame-rate 60fps would matter; I struggle to notice the difference. (In fact I wonder why I bought my new HDTV when my Elite and PS3 don't look that different!). To be honest I'd rather have some eye-candy over 60fps. Especially in a FPS.
