Right now he has the ems which is needed for rinnegan. But he also needs senju dna. So is it possible that Jugo gave Sasuke senju dna after he healed him?
So it seems he has all the tools but now he has to be near death. What I think will happen in the story is that Juubito is going to injure sasuke to near death, then Jugo will notice and go heal Sasuke with his dna (again) so this will give Sasuke more senju dna and he's already near death. This combination will cause Sasuke to awaken the rinnegan and then becomes more powerful and useful agaisnt the fight agaisnt Juubito.
With the rinnegan he would even with Naruto if they ever fight. Imagine how epic that fight will be.
