I decided to google Panopticon, and the result from Wikipedia says:
The Panopticon is a type of institutional building designed by English philosopher and social theorist Jeremy Bentham in the late 18th century. The concept of the design is to allow a watchman to observe (-opticon) all (pan-) inmates of an institution without them being able to tell whether or not they are being watched.
They mention some advert that talks about co-op games for Vita and that one was unspecified. So perhaps this is it.
Which, would be cool. Except considering how it looks, it may just be yet another game like Monster Hunter and the like. I'll still probably buy it, it's just I'd rather see a different genre.
