Assassins Creed 2 a PS3 timed exclusive?

I may be wrong here, but I certainly havent seen either a) A press release detailing platforms or b) a logo of which platforms its on at the end of any trailer.

They just said Novemeber 17th. And Sonys presser is still yet to come.

I MAY HAVE MISSED CONFIRMATION, but after a quick trundle through various sites and even watching the Ubi Presser, still no mention of platforms.

Now it wasnt shown or even mentioned at MS.

I dont have a PS3, so I want it on 360, and lets be honest, its way too much of a money maker for them to not release it on the 360, so its not a total exclusive, and it even makes a timed exclusive seen rediculous, but still, it does seem a little weird that I havnt seen any confirmation of platforms yet.

I WANT TO BE PROVEN WRONG ON THIS. Please, put my mind at ease with official Ubi info.
