Ubisoft make their games for the PS3 though, so it's easier to port over to the other platforms.

Before someone says "then why didn't they do that with Skyrim then?", it's because The Elder Scrolls, no matter which platform it sells the most for, is a PC game. You wouldn't like it if Xbox or PC stole your interactive movies such as The Last of Us or Heavy Rain, would you?
