It's obviously happening, wouldn't say it's confirmed though. People like to get technical and confirmed would mean there's no chance of anything else happening. Though there's barely a chance of NaruSaku happening, since this story revolves around Hinata, and Naruto it looks like. Can't wait to say "I told you so" to the fans saying "It's obvious NaruSaku will happen." The odds are literally like 99 percent NaruHina, then 1 percent NaruSaku, and that will just be a really random troll on Kishi lol, unless Hinata dies in this movie or something.
