I know what people have been saying after the last chapter, that Naruto will get Rinnengan when he get yin Kurama, and use this page as reference:
However that is just not the case here, Naruto cannot get a Doujutsu like rinnengan because of having yin Kurama back to yang kurama.
Infact what the Juubi saw in Naruto was simply an aura or will of Rikudou on Naruto because Naruto has the same relationship with the tailed beasts like Rikudou. It might be because it was made of tailed beasts that were friends with naruto now they are starting to remember that Naruto was their friend..
Anyway this is just a theory to stop those fanboys who are so convinced that Naruto will have Rinnengan
