Kilzone 2 is not a Halokiller, the problem lies with Sony fanboys that are so depressed by the sales of their console that they are trying to hail every new upcoming PS3 game (that has some extent of Hype behind it) as one of the biggest games that world has even seen.
We've seen some individuals claiming that LBP is a Mario Killer, That R2 is the best shooter ever, That Haze will be awesome, and that wii has no Games. And Killzone is just another "Wait until" title that PS3 fanboys are going on about it. It wont match Halo saleswise, it wont much it in terms of popularity and i really really doubt that it will match Halo or CoD in terms of quality (first Killzone is average).
I dont know how people expect K2 to become such a hit, when even huge franchises do not sell that much on PS3, i hope it's a damn good game but why hype it up so early and compare to such big name.
