Nope. If Resistance, Uncharted, MGS, and Lbp couldn't do it, nothing will convince Xbox players. In addition, most people don't even know what Killzone is, so I doubt this game will affect anything. As a matter of fact, I would expect this game to convince ps3 gamers to get a 360 because Xbox 360 has so many great shooters. This game could be a gateway drug for ps3 owners, which will lead to Xbox. I think the opposite affect is more likely. However, both situations are kind of a long shot.
