Naruto will get a rinnegan, u can count on that, he is going to become the 4th Rikudou Sennin. (not sure wtf Madara w/rinnegan fits into this, yet) I could give u a long explanation, but that would be off topic.
Yeah, I was kinda expecting Naruto to have a rinnegan as well. But with Madara having a rinnegan now, IMO, it's just bad storytelling if Kishi gives Naruto one too. It's being too redundant.
