It's funny that I thought Kishi was using TL logic while explaining the NH bonds to the interviewer about them being close before his bonds with Iruka started. But if you read his speeches again. Clearly he was referring to Sakura. She's the only female (his gen) that might have been close to him before Iruka, which was the hinted flashback in chapter 697 of her cringing when Naruto was about to get his bashed in by Sasuke during the sparring in the academy battlegrounds. And she looked depressed when Naruto was declared the loser, which suggested that Naruto and Sakura might have a dark hidden past that we will most likely never ever get, which was use as a red herring.
well I mean if the movie was in development for 2 years and already planned, then the ending was planned that long ago too, unless....what if the version of naruto the last we got was a last minute one made for all those fans spouting crap about naruto and hinata on the feedback pages and around the time kishimoto wrote this "ending"? what if the last really was a ns movie and then they changed it last minute over the months we got those supposed ns hints and stuff and that filler and the game were made around that time too and they threw the true love thing in the game for naruto and hinata and then just posted that filler unchanged like noone would care? I mean its probably easier to make an animated movie than to make one of those live action movies in hollywood I guess? idk...
You have to figure that Shuiesha/SJ played a major role in the ending, in which Kishi was allowed to end the manga because of NH (off the records). Remember that Kishi wanted to end the manga 7 years ago but was not allow to because the manga was very popular and at its peak at that time? Kishi came to SP, which he explain in one of his earlier interviews that he needed SP's help to flesh out NH.
Sure, the SP higher ups perhaps intentionally leaked this information about their females disliking the ending because NS never became canon, so they theoretically use this as an excuses to save their behinds if a council decisions is ever made in the future that the ending should deterred from the manga, and they point the fingers at Shieusha for everything. However, the higher ups did give the green light to mislead fans and rip them off with the false advertisements and the no refund. I'm sure there will be no remedy for that 
Shieusha no longer has any bearing on the story since the conclusion of the manga and SP has as all the rights to do with the Naruto franchise whatever way they want. So it will be up the the higher ups to determined this franchise's course. The only way we will know for sure is that we or someone must continue to the monitor the anime. The more we see hinted NS and SK rather if its fillers or canon episodes every week.
