I already have MW2 but that's my reason for wanting CoD 4. MW2, in my eyes, has been so dissapointing especialy from the big build it up seriously some of the things that happen with me and my friends are ridicoulous, We all have good connection it is never to do with our connection just to say but if me in my friend are in a party then every 6 out of 10 times we either end up in different games or we basically get kicked out of the game because what happens is when we join one another's game via join session it will epic lag then back on and say try to find new host: 1...2...3...4 but it eventually doesn't and just says game lobby closed but when you check on the PS3 menu they are still playing in the game and you are just sat they're thinking WTF!
