Not sure if this is to be believed or not but if it is true all I can say is
Now that Im done drooling you if you subscribe to GI, you can clearly see from the info box next to her arm that its the same as the GI format and its fuzzy but you can see that the first line for the Platform says Playstation Vita and the bottom says October 30 for Release Date...so if it isn't real, someone really put some effort into it
UPDATE: A 2nd image for it has been posted
SOurce: E3 2012: Assassin's Creed Vita Revealed? - IGNLooks like some secrets just won't keep until E3 -- if NeoGaf is to be believed. Over on the videogame forum, a poster claims to have the July issue of Game Informer, and inside are the first details on Assassin's Creed 3: Liberation for the PlayStation Vita.
Set between 1765 and 1780 and somehow involving 1763's end of the French and Indian War, Assassin's Creed 3: Liberation will supposedly cast players as a French black female assassin named Aveline. The details point to Ubisoft Sofia developing the game, it not being related to Desmond, and "multiplayer specifically tailored to the Vita experience." The poster said Liberation will launch alongside the console version of Assassin's Creed III on October 30th.
Ubisoft offered a "no comment" when approached for this article.
Of course, take all of this with a grain of salt for the moment as it is just information from a message board. If you have the issue of Game Informer, go ahead and confirm the details in the comments below. Otherwise, watch the Ubisoft and PlayStation E3 press conferences on IGN Monday to see if either party sheds some light on Assassin's Creed Vita.
