So this is how I think Naruto will end . . . or what will lead up to the ending . . .
I feel that it will climax when Sasuke finally fights Itachi and it is this life or death battle that we have all been wanting.
So what I see happening is Itachi is way too darn strong for Sasuke to handle on his own, because even though Sasuke has gained all this strength, I still think Itachi will always match and surpass him.
Really, I don't want Team Snake to be apart of this fight. I want Team Snake to just die or somethng, and what will happen is that Itachi is about to kill his brother once and for all, but Naruto shows up like he always does! and He tries to help Sasuke kill his brother . . . but Sasuke is all like No Naruto, get out of the way! and stuff like that, cause Sasuke wants to do this on his own.
So finally, Sasuke comes to the realization that he cannot beat his brother on his own, and he does need Naruto's help and somehow Sakura comes into the picture and it goes back to the old Team 7 days and they all try to team up and beat Itachi. and in the end, I think they succeed in killing Itachi or whatever it is they pan on doing.
with that being the climax, I feel that everything else that happens afterwards (falling action) will just be everything falling into place, like Naruto being Hokage and things like that, and with Itachi gone, how the rest of Akatsuki fairs . . . cause I do think Itachi's partner will definitely try to stop Sasuke and them from trying to kill Itachi, and I think Kakashi will take him on with Sakura . . . maybe that's how it would work so that Itachi's Team on Akatsuki is DEAD!
I don't think Akatsuki will succeed, they will come close to it, but their plans will be foiled somehow.
and in the end, I'm not sure that it will be the happiest moments, because my question is after Sasuke kills Itachi, what is his purpose in living? If he lives to kill his brother, he's no better than dead himself after Itachi is dead. Although Itachi is my favorite character in comparison to Sauske, I want Itachi to die to see how the hell Sasuke is going to live without the purpose of killing his already dead brother.
But I think Naruto will try to turn Sasuke back to Konoha, and it will be highly conflicting for Sasuke, even after his brother's death, especially now that Sasuke is like pure evil.
I know there are still a lot of questions that remain unanswered and I have a thought on how they'll be answered, but I don't feel like elaborating . . . it would take as long as those all those previous messages combined, so I'll leave it at that!
