According to one "spoiler" based on kishi sketches. In final fight sasuke takes control over juubi has rinnegan and some black rods sticking from his body kinda like pain. Every one is killed but sasuke and naruto. Naruto is supposedly 2nd coming of sage and gets some ass pull seals which helped him survive.
Sasuke then regrets killing every1, he's on his knees crying with naruto stretching his hand in forgiveness. Sasuke uses juubi power for rinne tensei and revives every1. Later naruto splits juubi into new baby bijus. And some other stuff i dont recall. Now i dont know if u also had this spoiler in NB XD
Anyway i can see that happen, madara could forcibly stick sasuke with rods or sasuke would accept them as power up
