Honestly, I don't think this game is that important. The PS3 has plenty of good shooters already; another one, even of very high quality, probably isn't going to do much to move hardware. I have trouble seeing someone saying, "I'm not interested in Resistance 1 + 2, Call of Duty 4 or World at War, and so on... but now that Killzone is out, I have to get a PS3!" A Feburary release likely isn't conducive to high hardware sales either.
Gran Turismo is overwhelmingly the biggest exclusive game in Sony's arsenal at the moment. If you want to talk about a game that is important to the system, focus on that one.
