EVEN IF Kishi proposed a NS ending, I don't trust him anymore. Think about it, NS in the pile of kitten that is the ending? NS in 700? NS like NH in The Last? It's not only the pairings that are wrong, WE GOT NO ANSWERS ON THE SOLE PROBLEMATIC OF THE MANGA! How to break cycle of hatred, how did Naruto become Hokage? How about Orochimaru, Team Taka, Kaguya, the Hyuuga Clan... He'll have to fix EVERYTHING and it's TOO LATE. Part 3 is coming so all that doesn't matter, we'll never have answers to those questions.
I trust fans more. Not kidding. We're not backed by anything. We don't have contracts, we don't have editors, biased assistants or studio.... And we have more respect for his characters and his story, we'd do it for SATISFACTION, not money.
Leave the man alone, he'll go on with his Bolt kitten, we'll do justice to Naruto.
