The presumed next iteration in the Jump Super Stars series, so far, the characters that have been confirmed are the three main characters from One Piece (Monkey D. Luffy), Dragon Ball Z (Goku) and Toriko (Toriko). Also, Naruto can be seen in one of the released screenshots, so he's there too.
I really enjoyed the Jump Super Star games and this certainly looks promising. But, yo, this won't be coming out in North America or Europe or anywhere that isn't Japan so you best be ready to import if you want to experience the madness for yourself. Good thing it's coming out for the PS Vita and PS3.
