Already been pretty much confirmed this chapter Sasuke will lose and receive a good beating for measure now I understand what those bandages on his head are for
It was foreshadowed that sakura has to make a choice to heal one of them. Even I there first fight.
She'll heal sasuke first, because Naruto is durable, and will most likely still stand after being beating ( draw) because he fights with the power of love
It ends the same way hashi and Madara's battle ends nah jk I wouldn't mind tbh, if both were tied it wouldn't matter to me as the battle itself would have been so epic it wouldn't have mattered.
Lol "peace" there will just be another madara or another indra eventually or someone more evil, human beings aren't exactly the most....peaceful people
None of them will die ,also naruto can't fail achieving his goals to bring sasuke back ,also his promise to sakura ,hagromo also said this time he hopes hate will turn to love
So I think naruto will win and then tnj sasuke
