halo Wars sales will be huge for it's genre - bigger than killzone 2.

[Gabriel84]

well xbox 360 has a bigger user base, and judged by what MGS4 did (a mere 3.7 million according to this website), k2 should do around 3 milion this year.
I can't see K2 will bcome a bigger hit than MSG4 to be honest.

we'll see about that
