Okay, so it's probably more fair to say J-Stars Victory Vs is like Power Stone with anime characters. Or really, like any of the Dragon Ball Z games, but with a bunch of characters from other shows like One Piece, Naruto, Bleach, and a bunch of others I'm not familiar with at all.
Looks fun! Namco Bandai is behind this one, and it's planned for the PlayStation 3 and PlayStation Vita. Possible western release? Doubtful, seeing as half of the roster that was on display in this debut trailer have yet to make an impact outside of Japan.
