What do you think will be the ending of the anime naruto?

Most likely an all-out battle between Sasuke and Naruto since Sasuke works for Madara now, then Sasuke gets injured or something and Naruto goes on to fight Madara, then defeats Madara. And in the end, Naruto goes back to find the injured Sasuke but can't find him anywhere... and years later when he's the Hokage, he still vows to find Sasuke one day the end actually I have no idea how Sasuke's going to go back to Konoha... and Naruto's not gonna give up on him
