I'll refer to the developer comments explaining development on the PS3 results into better designed and thus better performing 360/PC gaming engines as well. Combine this with the comments from the Ghostbusters guys who are leading their project on the PS3, claiming they would have been able to twice as much onscreen if the game would have been PS3 exclusive.
They think the PS3 is far more powerful as do many other developers, read the NeoGAF thread linked below for a collection of many different comment and collection of information.
