Yes, and I think in the end he wasn't man enough to stand behind the empowered woman he created. He had to dial her back because she was 'too severe.' Of all the characters Sakura is the one he has consistently defended or apologized for in interviews.
She is the only one that is picked on and picked over. She is the only one that gets this treatment, not Naruto who is never tested, nor Sasuke who is never responsible for his truly terrible behaviors. And not Hinata who just passively worships the hero, to the point that her only actions in the story are for him, and him only. None of them get an iota of attention, but always Sakura.
I think on one hand Kishimoto is wrote her as a modern, determined, honest girl, as he said in an interview long ago. But I think outside pressure and his own discomfort with the idea of an empowered woman taking the lead won out in the end. He couldn't take it. It didn't fit in with whatever stereotype for women's roles he had in his mind.
And now, Kishimoto's not only demoted Sakura to the Part 1 girl with a crush who accepts Sasuke no matter how badly he's treated her (699), he's given the final illustration of her in the manga as a housekeeper/housewife (700). He's put her in a role that's against everything she ever wanted in the manga. And now in the movie, her biggest promotion was in the release of her sketches with Naruto's in Kishimoto's final troll pairing them together for the last time. We haven't seen her since then. It's been all about Hinata.
He's so uncomfortable with Sakura's empowerment, he's got to render her irrelevant to the storyline. It's all about passive Hinata, in a passive romance movie that sounds like a terrible fanfic. She's kidnapped and that's what awakens Naruto's hidden feelings? Come on, how much more passive can you get?
At some point he didn't just decide to make the ending NH. He decided to use Sakura to dupe the audience into sticking around till then end. He even used his main character as a plot device, with his devotion to Sakura registering a loyalty with fans that Kishimoto knew he would never honor.
Only Sasuke gets what he never wanted. And Hinata gets what she doesn't deserve.
Sakura and Naruto are left out in the cold.
You're right. Kishimoto knew exactly what he was doing, building up NS over and over again, reinforcing it with parallels and moments together. He was building it up for a bait and switch, using half his fan base to make some extra money on the opposing shippers.
In the end, I don't think Kishimoto supports any pairing. Because he didn't care to develop SS or NH at all. I really think he just doesn't care.
The movie animators are doing this movie, not Kishimoto. And the marketing promos are coming from other people, not him. So the release of a book that sums up 700 chapters in 15 pages, connecting the dots for a cheat sheet to an NH romance that was never there, means nothing to him. Because he doesn't care. About NS, NH or SS.
If he cared he could have developed any of it in the intervening years. But he didn't.
The only thing he's proved that he does care about is not making the female roles to strong or self-actualized. Mass murder, obscene violence, emotional rejection, psychopathy, abuse of children, medical experiments, even stealing eyeballs — all things that Kishimoto has never once apologized for. But Sakura? She's 'too severe.'
Sakura's not the problem. Kishimoto is.
I wish I could like this post more than once. Absolutely spot on.
