I don't think that these three exclusive titles will completely negate a sales boost in favour of the PS3, irrespective of dwarfing advertising campaigns or brand recognition of the 360 titles. Killzone 2 is bundled in Europe, so theoretically bundles should move more consoles. It's still a good strategy by MS that will likely hinder some momentum that Killzone 2 would have had should they not be synchronized releases.
