Sony doesn't need to spread this engine around. All of their first party studios use their own proprietary engines, and they share tips and tricks with each other to make the most out of each engine (for example, Naughty Dog received help from Guerrilla to decrease the flickering shadows in Uncharted).
Evolution Studios haves their own engine for MotorStorm (MotorStorm was the first ps3 game to have dynamic shadows on every object in the game, fyi), Sony Liverpool have their own engine, Sony Santa Monica have their own engine, etc. etc.
I fully expect Uncharted 2 and God of War III to at least match Killzone 2 in most areas, if not surpass it.
