I doubt it.....Kishi has been imho writing him horribly lately. I cannot complain... as this is Kishis work, he has that right. I just feel he is bored of playing with Madara....like an old toy.

He had the potential to rival the greatest villains.... Like Cell, Aizen, Frieza, Sesshomaru, Shishio, Light, etc. Though.... Imho Kishi ruined any chance of that starting with chapter 644 to currently.
Though I still feel that in Naruto he is the best villain by a substantial margin. With Pain, Oro, and Tobi(Not Obito) trailing behind him. I just think Kishi is finished with Madara as a plaything. Maybe..... Kaguya will emerge, but Kishi isn't daring enough to let a villain win so she will suffer the same fate as all Kishis villains.
That's why I get mind boggled when ppl say she will be better when she will inevitably be defeated and humiliated like all villains in this Manga. I just feel Kishi wants a cliche ending.... something we expect. Naruto and Sasuke fight for Hokage, one loses leaves the village, or its a friendly bout...happily ever after. Imho these would be so boring to me.

Maybe not though..... I'll just have to wait and see. XD
I don't think Kishi will give him his eye.....and if he does it won't make a difference... He will write Madara in a nerfed manner so Sasuke and Naruto win. XD
