The whole deal about the Jinchuriki spirits has been pretty much the entire focus of Naruto Shippuden, and even then the anime hasn’t even gone too far into the other fox tail spirits (outside of the 9 and 8 tails). Regardless of this, CyberConnect2 as decided that including all 9 of the Jinchuriki (obviously including Naruto) was a good idea, and I for one agree. You will be able to play as all 9 of the characters that have the various tailed beats inside of them in the main game, and each will also be available as playable characters in the arcade. Each one of them should be interesting to use, considering they must have some crazy power boosts because of their beasts.
CyberConnect2 also announced that anyone who has previous save data for Naruto Shippuden: Ultimate Ninja Storm Generations will gain access to a Hokage costume for Naruto, as well as that they will be unveiling a new trailer at Jump Festa later next week.
