As the picture attests, these images are from psvitahub and allegedly show a version of Tekken Tag Tournament 2 for the PlayStation Vita, a port of the game that is yet to be confirmed. You can see it right there, somewhere underneath their web address.
This would be yet another game getting both a PS3 and Vita release, hinting that perhaps the next fad will involve buying two copies of the same game so that you can play both on the road and while at home.
Another image shows the character selection screen and shows that Tekken Tag Vita, at this point possibly fictitious, will support NEAR – meaning online play.
Take it with a pinch of salt, although it's not a completely mad idea.
