Imo the following theory would be in line with the style of Kishimoto:
It would be pretty awesome, if it seems like Naruto won against Sasuke and after a TnJ Sasuke becomes good again.
Everything seems to be perfect and Naruto becomes Hokage with Sasuke supporting him as a friend.
But someday Naruto recognizes that the world feels strange and sth is wrong.
Then it will be confirmed that Sasuke caught Naruto inside a genjutsu during their battle.
But as in their previous fights, Sasuke can't kill Naruto, instead he keeps him inside his Genjutsu, which is similar to infinite Tsukuyomi.
Somebody (e.g. Konohamaru or Sakura/Hinata) finds Narutos body (hidden by Sasuke) and he releases him from the genjutsu.
He tells Naruto that he lost against Sasuke, and Sasuke killed the Gokage and the Bijuu and made his Revolution.
Now he rules the world like Hitler, and nobody is able to do anything against his power.
Naruto in ultimate anger mode goes for Sasuke. On his way he sees the world in a terrible condition, which makes him even angrier.
After an other epic fight and a Chidori-rasengan clash, the losing Sasuke realizes that he became the darkness himself, that he tried to protect the world from.
He rinne tenseis the Gokages and leaves the duty to bring peace to this world to Naruto.
The second part could also be the plot of the movie.
What do you think about this theory?
