My guess is that this is the next Assassin's Creed Vita game. Probably with a Native American lead (and HOPEFULLY, a cameo or co-op with Aveline from AC:Liberation. She's my 2nd favorite AC lead behind only Ezio, of course.

What do you think this is?

Here is the confirmation article: http://www.computerandvideogames.com/396307/assassins-creed-rising-phoenix-is-a-ps-vita-title-online-listing-suggests/

TOLD YA! ha! jk 

Might be a Vita game. But in that case it won't be released anytime soon.

I definitely think it's a Vita. And I think I have to disagree with your "no time soon" assessment. They already have the Vita engine from Liberation. All they've been doing lately (with all AC games since AC:II) is taking that engine and implementing new stories. I wouldn't be surprised if this comes out at Christmas.

Vita's AC didn't sold that well to warrant a sequel. I believe that's another mobile game.

3DS title, hey it can sell alot!

Why do people on this site always type what I was about to type? You're stealing my thunder!

Every game is a Vita game until proven otherwise.

Yves Guillemot said the complete opposite.  Hmm who to believe...a random internet poster biased aganist Sony or the CEO of ubisoft?  Damn why do these choices have to be so hard.
