Vgchartz must be way overtracking these consoles, since the there are only 338 gamers according to that poll.
Seriously, I could post in a MS fanboy forum asking whether or not Halo 3 was the greatest FPS this generation, and I guarantee that "most gamers" think Halo 3 will be the FPS of the generation.
My FPS of this year will be MW2 if it's as good as MW1, I personally don't believe KZ2 > MW1, both are great games though.
I can see why people would pick KZ2 though (aside from being a raving fanboys of course)
