I think I'm changing my bet on how the manga's gonna end, far in the future, I hope. Up until now, I've said Naruto's gonna save Sasuke. Well, I've been reading the chapters from the very beginning again, and I'm up to where Sasuke leaves. Now I see more clearly the relationship between the 3 sennin, Naruto, Sasuke, and Sakura. I think that Naruto will break the coincidences and kill Sasuke in the end. That'll be his final growth/maturation. He'll finally realize he HAS to make some tough decisions, and that'll be his. We'll see. This isn't a new idea, just a change of view on my own. I always thought Sasuke was still kinda good, but I bet he falls even further into the darkness... Too far. Well, that's what I think now. And it should be the final battle.
