Interesting topic. I have also considered that Naruto would somehow get the Rinnegan. But my theory comes from those fist bumps Naruto got from all the Bijuus. Does anyone know if something has occured because of that? My theory was that they imprinted their souls or something in Naruto, and that he would awaken something, be it Rinnegan, BM combined with SM, become a type of 10-tails jinchuuriki himself, or maybe even that the SO6P would be resurrected within Naruto or something. Anyone have any thoughts?
