Also holy crap the cutscenes on the PS3 version are 60fps. That is a pretty big difference.
Example: The scene where you walk into the room and several monsters rise from the floor around you, when the Ice Demons appear for the first time, or the first time you walk into the building to look for the drawbridge switch. Seriously if you own both systems check that out. During the 60 fps cutscenes, sometimes it drops back down to 360 version cutscene fps for abit, but for the most part it sticks to 60fps.
After playing the 360 version and making my way through the PS3 version demo...thats about the only difference I see image wise, not that it's a deal breaker of any sort, but it's still there...so whatever.
The controls of course feel a little better using the good ol dual shock/sixaxis for DMC action. But thats the same way I felt when playing Ninja Gaiden using the PS3 controller, that just felt better with the 360 controller/original controller style.
