After this chapter I can kind of see what powerups Kishi is prepping for Naruto and Sasuke.
If you remember, back when Naruto was fighting Tobi he ended up getting the chakra of Tailed beasts 2-7. Obito just got some of the chakra of the 1, 8, and 9 tails and is in the process of giving it to Naruto. So that means he'll have some chakra from each tailed beast...you can probably see where that's going. Sage of the Six Paths Naruto coming soon.
As far as Sasuke, he's about to be in the same situation that Madara was once in. Has EMS, is on the verge of death, and is about to have Senju DNA implanted in his body (pause). That combo of factors unlocked the Rinnegan for Madara so it'll probably do the same for Sas.
So basically, it'll be Six Paths Naruto and Rinnegan Sasuke vs. Madara.
