PS3 fans shafted by Ubisoft again?

Assassins Creed is one game which seems to be famous more for its exclusivity debates rather than gameplay demos- the game was first announced as Project Assassin, an Xbox 360 title, and then revealed to be a PlayStation 3 game. This sparked controversy amongst fans, with PlayStation fans claiming that the game would be a PlayStation 3 exclusive while others argued that it was only a matter of time before Ubisoft announced that the game would appear on other platforms.
