Assassin's Creed (It was exclusive at first)

nope, made on 360 engine and ported over.  problem with a lot of early games this gen is the 360 had the dev kits out way before sony.  So developers would use those dev kits to make the game, and then port it over to the ps3 when they got the ps3 dev kits.  Assassins creed was this way. 

I believe PS3 dev kits were already out before a 360 version was even announced.

could have been, it doesn't mean that the game hadn't been in development for a long time before that.  Ubisoft started making that game when they got the 360 dev kit.  If you recall, it was first shown off as an xbox 360 game at the X05 event.
