just here asking if anyone thinks that Naruto will get the Rinnegan. and if Sasuke will get the other Rinnegan. It is my theory that in order to beat madara they both will have to have a Rinnegan. my main theory how is that hashirama will show up on the battle field and will inform them that in order to beat madara they both will have to up the playing field. so hashirama will give sasuke his chakra and DNA causing sasuke to awaken the Rinnegan in his right eye. but because Madara has the holy tree in him they will still need more power. Hashirama knowing Naruto has the same power as him will say that Naruto needs the eyes of the sage as well so sasuke will tell Naruto to steal Obito's eyes Naruto will say something about how obito may have started this war but he is good in the end. but sasuke will say shut up Naruto we can not possibly win with out this so naruto will go after zetsubito eventually Naruto will defeat zetsubito take the eyes(at the same time remove zetsu and revive obito and heal his eyes) then once he puts obito's MS in him i believe since he actually has the full on body of senju(as well as the senjutsu of the six paths) his eyes will evolve instantly(he will also be able to turn them off and on at will) which will allow them to turn the tide
so what do you think? i know it was a bit long winded but just stating a a theory on how both could gain the eyes
