I think with Oro stating he wanted Sasuke's body after being revived and him going to the battlefield after saying he wasn't interested in the war indicates that the Naruto vs Sasuke fight will still happen. It's possible that Oro could take advantage and steal Sasuke's body when the war is over. Oro is always schemin'!
Yes there will be one last fight between them but I think that the one with powerful eyes that Naruto will 'meet' is the sage of six paths.Here is why, we all know Kishi doesn't talk about a character we never seen before for no reason.Like what he did with the real Madara, nobody saw it coming so my guess is that the sage of six paths will make an appearance.
Madara: Good>Bad>good>bad
Sasuke: Good>Bad>Good?...
lol anyways, he probably didn't just instantly loose all of his hate, and the "curse of uchiha" lingers in his soul. Also with the prophecy and all of the foreshadowing, There most likely will be a big fight
naruto said he knew from there last clash they will both fight and both die. ethier the truth or naruto was just sayin stuff to show off infront of sakura...lol
Sasuke will fight, but when the fight is over, Naruto will say something dumb (not dumb, but it will be something as a joke against the Uchiha) and Sasuke will become evil again.
Je ne sais pas. I don't think Kishi is going to cancel the Naruto vs Sasuke fight, but he probably will change the meaning. Instead of a fight to the death with dramaz and suspense, it'll probably end up as a friendly battle to test each other's strength.
