nah sauske will turn back against madara with naruto imo, for the fate of the world ect, they kill madara and sauske leaves again to prolong the series imo
This is a possibility. I think the most likely one is that Naruto decides he has to kill them both, and he gets Madara first, then fights and kills Sasuke.
