Fez running on a Vita, just about

See those few pixels in the middle, that's movement that is. Meaning this isn't just a screenshot plastered on a Vita as a joke. It comes from Polytron's Twitter account, so has to be real right? You can just make out the hero on the same platform, and the whole thing looks pretty much like the Xbox version. Just how much of it is finished though? Lets hope we here some more details soon.
