Its not how good it is, its actually the tecnology and the 256 people gaming together that makes it impressive and I hope they sell this tecnology to the likes of IW and the next call of duty could be mind blowing...
On the other hand bayonetta for the ps3 is getting really bad reviews and if you have a 360 you should get it for the 360. Now a lot of good games are coming out in the next month too like bioshock 2, and we are getting final fantasy and white knight chronicles in march so dont go out and spend all your money.
Also we had a great run in autumn with the releases and exclusives like god of war collection, uncharted 2, and some other great gems that are multiplatform like borderlands and mw2. So many games, so little time, Im almost done with my platinum trophy on mw2
I agree with the guy above me. The ability to do all of this at once is amazing. And COD will be amazing if they implement it!
