I'm not going to get into this because the Naruto/Hinata fanbase is legitamately crazy, but until I actually see a scene from the movie straight up showing them being romantically involved, I'm not going to trust rumors and assumptions.
Partly because I JUST watched a whole scene of Minato pointing out the Similarities between Sakura and Kushina and Naruto trying to say that she is his girlfriend, so that would be a little weird from a writing standpoint to be pushing this Sakura/Kushina thing for as long as Kishi has and then turn around and be like "Never happened!"
It's bandaged completely in the concept art, so I think he got it back but it's mostly busted in battle.
Mostly busted? It wasn't there! It's gone. Then again, Naruto.
