How important is Killzone 2 to the PS3?

I think its a big title for the PS3, It could give them the shooter franchise they can all there own, just like MS has with Halo. It will move a pretty good amount of consoles for a week or 2, probably in the range of MGS4. I do expect this title to surpass the 3 million mark by the end of May.
