I have a feeling that Naruto, either during the war or after the war will become the ten tails jinchūriki, Everything that we have read and seen is pointing towards that. During the new chapter the SO6P said himself that one day they all will become one. I think that will happen within Naruto. Also I think when that happens or before that happens the Sage will apear before Naruto some how (because there is a rumor that the Sage sealed either his soul or part of his charka (like naruto's mom and dad did) inside the nine-tails). Any thoughts?
