Newcomers up to now just include Sai and post-time-skip Sasuke...
hopefully they'll add Sasori without Hiroku plus the rest of the original rookies... sadly I don't think they'll include Kakuzu, Hidan, Zetsu and Tobi... not to mention Pain and Konan... I'll probably wait until the fourth part of this game when all the above appear... I did it with the original narutimate volumes...
