I think Naruto will awaken his own Rinnegan !!!! :P
Its true that nartuo has come along way. Since he is now a sage, But one of the things that kinda of stuck was what Fukusaku said. Yes I know Naruto has mastered much of the Sage Techniques, a lot better then his Predecessor Jiraya. But he has not totally master it yet. Until Naruto truly grasps the risk of Sage Mode he can't unleash it true power. Here's my theory that in order for Naruto to truly master sage mode he has to awaken his Rinnegan and that if he has it.
