I received it in the mail yesterday, and played some last night before I went to bed. Its a pretty good experience, the graphics look just as good, or even better than what I saw in CoD4. The first thing I noticed that was sort of weird was the Co-op screen. Its still a horizontal screen but it doesn't fill up the whole half screen. The rest is backdrop. This makes it pretty hard to see because I don't have the best TV in the world to game on, but it was pretty fun anyways.

I haven't got onto online multiplayer yet because I was busy breezing through the campaign(to the last mission) on Co-op but I guess I'll get to that today.
