Makes no sense imo. If anything, Sasuke will take Madara's eye in the end. As much as I'd like it to happen and for Sasuke to get what he deserves, it makes zero sense from a plot standpoint to go through the whole thing with the sage and Naruto and Sasuke and the reincarnations and giving him the power just for him to lose it a few hours later. It's a lose-lose situation imo because I want Sasuke to be stripped of everything and rot in a hole, at the same time it would be piss poor writing to go through all that just to take it back. Then again, it was piss poor writing to give Sasuke anything, but at least it would be consistent with Kishi's awful writing. I just don't see it happening at all.
