I was wondering if Naruto having the 9 tails inside of him is some how preventing him from obtaining the rinnegan. I think Everyone would agree that Naruto is the Sage of Six Paths incarnate. So eventually he has to get the rinnegan . I think it would be cool if Tobi steals the nine tails away from Naruto.
Then Naruto wouldnt have to rely on the nine tails so much and could use his own power.
