"Exclusive has become my new favourite word," SCEA CEO Jack Tretton just said. The platform tit-for-tat hasn't ended yet, as the executive just revealed that Ubisoft is working on some new Assassin's Creed related content that will only be available on the PlayStation 3.
Quite what that content will be is unknown, but the announcement coincided with a lengthy trailer for Assassin's Creed Brotherhood, the sequel that will see you sneaking around killing yet more people. It'll be lovely.
A release date for that title came with the trailer. It will hit on the 16th November 2010.
