Sony have published Resistance, Resistance 2 and KillZone 2.
M$ have published Halo 3, Perfect Dark and Halo ODST.
Nintendo have published 0 FPS this gen.
So its safe to say that is just a 3rd party phase that will pass like every other genres. What bother me is that Sony is publishing more and more FPS then JRPGs this gen. I would like to see Sony go back to a diverse library.
