I think it will give it a bump in places like UK where there is a bundle out for it. If i didn't already have a PS3 i might have been tempted to go for it. But i think they could of done a bit more with it. A few weeks ago we had bundles where you could get a 80GB PS3 with LBP,Far Cry 2 and a Blu Ray film with remote. All for £299. If the bundle swaps to just KillZone 2 and the PS3 for £299 i think it won't shift as many as it could if it kept either a Blu Ray film with remote and another oldish game in the bundle.
The reality is the game is not this all amazing genre changing FPS game that so many claimed it would be. Reviews are very good for the game but it is now out scored by SF4. I think that game has got the potential to be massive so that could damage sales of KZ2.
So i would expect WW sales for the PS3 to bump a bit, but i also expect the 360's numbers to bump a bit to, so it will cancel each other out.
