I can see a happy yet sad ending
sasuke change his mind and helps Naruto fight tobi and dies trying which set Naruto off and he kills Tobi everyone else win their battle
(he would have started going out with Hinata)
at the end it would show Naruto years later as Hokage looking out the window and flash backs of his life and how hard it's been then show all the friends he made along the way and start thinking about the ups and downs with everyone of them and like always sasuke will be the main one
then in the sky it will show a Picture of His Dad,his Mom, Jman, Iruka, Kakashi, and Sasuke
then slowly fade out
I know sounds stupid because I didn't really explain but hey if you want me to I will write my own ending to the manga and let you read it
