Gamepro -- Killzone 2 VS Halo 3 (Is KZ2 a Halo Killer?) YES IT IS!!

[KatinJin]

KZ2 first week sales ~100k in the UK.
Halo 3 first week sales ~460k in the UK.

Does that seem like a Halo killer. I think not. Extra days week one aside, when it can pull in $300 million week 1 then we might have something to talk about.
