Killzone 2 will be a massive game. I'm not sure how it will fair online though as people have got into the habit of the COD games where it's very fast paced run and gun effort. Killzone will need a bit more tactics and less running it with your finger glued to R1. It'll take alot to knock COD4 out of my machine but I do believe Killzone will be the game to do it, I've been looking forward to it for over a year and the closer it gets the closer the pee is to running down my leg with excitment.

As for GTA IV, simply put it's one of the greatest games ever made. IMO <-- Better put that in there..!
