That's on some DBZ/Bleach type stuff. I'm sure we'll all get a sneak peak into the future.Ending would be like sasuke & naruto get exhausted
Fight against madara. Madara will using final attack to kill naruto & sasuke suddenly asura & indra spirit come in both of their mind they said u both can do it & then other shinobi spirit come in both of them & they give their power to naruto & sasuke to kill madara they also
Prepare final blow. Naruto & sasuke & madara clash their final power & then boom after the dust clear winner is sasuke & naruto
I guarantee Madara will succumb to TnJ and Kaguya will possess him and that's will be the final battle
then we will get a few a epilogue chapters about what life is like after the war and what changes Naruto and Sasuke have made to the ninja world.
Then a final epilogue chapter about what Konoha is like when Konahomaru is the 7th (or 8th) Hokage. He can't just leave us hanging on what Konahomaru is like when he is Hokage or if he ever reaches that position
