Factual Evidence:
It is confirmed from Shonen Jump, the publisher of the number one manga, Naruto, that it will reach its conclusion on November 10th (Monday). November 10th is the day of the manga release in Japan and for subscribers of the Shonen Jump. However, scans on the internet will receive the manga on either November 5th or the 6th. That means that for a majority of us, our beloved manga will reach its end on a Wednesday or Thursday. This confirmation is probably directly verified with Kishimoto too. Therefore it is 100% legitimate.
Plot Ideas and theories:
I believe that the fight will be very one sided for it to end this quick. Naruto will end up a victor, however Sasuke and Naruto will make amends. Of course this is a generic cliche ending.
Another possibility is that Naruto TnJs (Talk No Jutsu) Sasuke into turning good. Sure they fight but only for a while. The fight will be more meaningful than full of action. Sasuke will ultimately be swayed by words.
Lastly something else utterly different may happen. Who knows. Surprise me. I really hope that there is enough time to wrap things up. I'd wish to see sentimental moments of Jiraiya, Minato and Nagato. Whatever happened to the Ninja tools near Tenten, Infinite Tsukuyomi, Kaguyas needed army, Madaras dead body?
We knew it was coming. But 5 weeks. Are you kidding me? This news to me was shocking. Utterly shocking. I thought Naruto would last for an additional fifteen chapters or so, at the least. At the moment, it is the final battle, Naruto v Sasuke. It has just begun. Literally, the last page of chapter 694 shows Naruto and Sasuke exchanging fists. That's it. Now we will have to expect this fight to reach its conclusion in five chapters alongside the wrapping up. How will that happen? God knows. However, i trust Kishimoto to wrap it up sufficiently and no matter what or how it ends, Naruto will go down as my favorite manga.
What does the Naruto ending mean to Naruto fans?
Well, for starters some people have been with Naruto for about 15 years. In my case, i've followed Naruto for eight years. That means that i've grown up alongside Naruto and his adventures. Many of us did. It is definitely sad to see it leaving. To me, it's like my best friend, a childhood best friend, leaving for good. The thought of it ending is very daunting. If i could, i would like to sit beside a lake and just stare into the waters reflecting upon my life and how Naruto influenced and entertained it for so long. No matter the ending, for better or worse, Naruto will always be part of my history in a good manner. Naruto is simply...irreplaceable.
