sasuke swears to fight naruto, leaves on a hawk, naruto goes back to village, marries hinata, sakura's either dead or long forgotten, kakashi becomes hokage with shikamaru and naruto as his associates
naruto and killer bee kill tobi and his six paths then killer bee leaves to help A, while naruto goes to hinata, once he gets there we see him and hinata having *** after this the war ends, because itachi killed kabuto and sasuke died in that tragic spoon accident, the world is at peace, and everything is right
I believe when this war ends, they will have another time skip. Naruto will be Hokage and all the people in his year will have some substantual job. Both will have survived their fight and Sasuke will be the main antagonist or Oro will find another way to come back and be the badass antagonist again.( Nothing is impossible with that guy lol)
The story will go back to focusing mostly on Konoha like in part 1.
I honestly hope they have a season or something where they explain and give backgrounds to characters like Kakashi's father or Hiruzen.
Well after sasuke dies sacrificing himself or faking death naruto will go back to konoha and then another major villain will appear. Or they live happily ever after.
Then naruto will have a kid and the new series will be called jiraiya, minato or sasuke
