Alright, so we all know that by the chapter, Naruto is continually getting foreshadowed that he is going to resemble Rikudou.
Secondly, we also know that Obito has done more eye transplants than any other character. (Gave a sharingan, got a sharingan, got a rinnegan, helped Sasuke with his eyes, etc)
Now here's where thing's become extremely late night rambling. So when Naruto TNJ's Obito back into OG Obito Uchiha and most likely does his inevitable self sacrifice: What if he decides to entrust Naruto with the Rinnegan
The last time good Obito thought he was going to die, he entrusted his best friend with his eye. Since Naruto is supposed to be the next Rikudou and Naruto is about to convince Obito he is the savior of the world, why wouldn't it cross Obito's mind to give Naruto the Rinnegan in his last moments?
Tl;dr - Obito give Naruto Rinnegan?
