FPS on ps3 just as popular as on x360?

[Reasonable]

I think the PS3 install base isn't quite as FPS centric as 360, however it clearly can support a decent FPS community.

I note that big titles tend to sell roughly equally in ratio to the user base, while smaller FPS will tend to sell better on 360 in ratio to the userbase - i.e. PS3 owners like FPS, but big titles apart are somewhat less likely to want to get every FPS going than 360 owners.
