Still slated for a Summer 2015 North American release, J-Stars Victory vs+ is basically a fighting game with no less than the Best of the Best from Shonen Jump manga. Seriously though, this game will have it all; One Piece, Naruto, Bleach, Dragonball Z, Ruruoni Kenshin, Gintama, Hunter X Hunter, the list goes on and on and on and on. The game has already been out in Japan for about a year, but given the growing popularity of various Anime in the US it was only a matter of time before they localised it for release. The first major release videos have finally come out (including Dragonball Z, Dr. Slump, Tottemo! Luckyman, Beelzebub, and Chinyuuki), and you can see them below:
Here is a video of the Japanese version too, so you can see just how crazy the action is going to be:
