I haven't played it, but my 360-fan friend has played it, and gone on about it for weeks.

The graphics look immense, and I like the fact that you can take cover.

He loves it - he sat down and bombed through it in about 8 hours. Last time he played it was a 3-hour stint of co-op with his brother.

I'd like to play it just to see if it's as good as everyone says.
