This could potentially be a spoiler, though who knows?
I was thinking today at work, that in the end sasuke might possibly end up dying. Now this is not sasuke hate or anything, so just lend me your ears for a second. Even tho sasuke has decided to change his ways, there will be nothing left for him after the war. I doubt the other villages will so easily forgive him after all of the crimes he has commited. The Uchiha clan is definatly a clan that is distrusted and in some cases, hated. So, what if, in the end, sasuke sacrificed himself? Not only for Konoha, but the entire ninja world? Not only then would his clans name be restored, (albeit gone), People would actually think of the uchiha with gratitude, and respect. It would also push naruto to grow up a little, which he is sure as hell gonna need if hes gonna be the Hokage lol. Look at all that paper work hahahaha. Either way, just thought I would share.
