Considering the first Killzone was supposed to be the first "Halo-killer" and it ended up turning out to be a pretty mediocre game and which I thought was sub par, besides FPS games on DualShock controller = Projectile vomit
Two incredibly over-hyped games going head to head... hmm. Halo is going to win, fan base is way too huge and since there are much more 360 consoles than PS3 consoles I think there isn't going to be much competition.
