A good way to decide would be to consider the sales of the last full games in the series (24th Jan)
Halo 3: 10.74 million and top selling game on the Xbox 360
Killzone 2: 2.19 million and 17th best selling game on the PS3
No comparison, even with a comparable userbase, Killzone 3 doesnt stand a chance. And lol at whoever says Killzone 2 is a Halo killer
