Well I have the game and I've only played about 4 matches online but I must tell you that so far it is more rewarding online than COD. The only thing I'm hating is all the snipers, but this is a teamplay game. You can mark enemies fairly easy with drones that you purchase with Battlepoints so campers won't last long in this game. The Battlepoints concept is awesome. Sooo much better than killstreaks. Its worth a purchase if you are a MP fan. I haven't touched the SP yet.
Graphics wise its a step down from COD so I don't know why he compared it to KIllzone 3 and Crysis 2 which are setting the benchmark graphically for consoles. I agree with the 6.5 on the graphics. They aren't terrible but they are on the level of shooters from the beginning of this gen and not shooters coming out now.
Overall graphically mediocre or not I think I'm going to like it better than Black Ops. This game should have gotten a 7.5 minimum possibly even an 8. Black Ops should have gotten the 7.
