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

Using Amazon as a ruler is like using the scores from IGN as a basis for what games you buy... and I'd have this comment about half the forum but then I'd get banned :p.

OT: I think Halo Wars will top KZ2... I seriously doubt KZ2 will do WaW numbers and I think that HW will do close to Fable 2 numbers.
