Looks like "Assassin's Creed 4: Black Flag's" creative director Jean Guesdon has some insider knowledge about both Sony and Microsoft's next-gen system. During an interview with OXM, Guesdon let slip that the next "Creed" is set to ship for all consoles at the same time. See for yourself below at the 5:42 mark.
The "same time" Guesdon is referring to is the date listed on the Assassin's Creed website, October 29th.
Interesting, as when Sony presented their new console, they hadn't mentioned an exact release date, just "the holiday season of 2013." Likewise, as we've yet to hear anything from Microsoft in regards to their new console, an October release for both consoles seems awfully quick.
Is Guesdon correct, or is there a bit of miscommunication? Only time will tell.
