Well Kishi said that Naruto was ending in the near future in a interview last year plus he even sent out a message saying thank for following the story of a boy named Naruto as it comes to end, but there are rumors that he might not end it because Apparently ( I not sure where this is from the other I can confirm but not this) Kishi said when he ends Naruto he'll have nothing to do with himself. So maybe it will keep going
After the battle they could do a time jump. When naruto & sasuke are older and have kids with the women they settle down with. They'll show the ninja world is at peace and no one is fighting amongst themselves.
