What happen to Naruto and Hinata now?

It was nothing really minor, Obito killed his friend and tried to turn him over to the darkside (sorry for the Star Wars referance) But Hinata was there to gently slap some sense into him, she helped Naruto realize what he was saying was no lie and that they share the same views and helped him realize that she was always there for him.

you really should go to mangapanda.com, Naruto chapter 615.

what happened afterwards was this, Naruto moved his hand towards Hinata's grabbed it and realized that Hinata will always be by his side, he stood up with the memories of everyone that made the ultimate sacrifice for him, he thanked Neji for everything then while holding Hinata's hand he thanked her for being there every step of the way.

on the last page he said he would never let go of her hand while Naruto and Hinata stood in the middle of the battlefield ready to charge at the Juubi, with Kurama fully charged and ready to go for the final part of the battle

what that basically means NaruHina is pretty much confirmed.

Nothing much. Hinata getting development. The Naruto and Hinata thing is nothing, just a support from Hinata.

Nothing is happening with Naruto and Hinata except a bunch of NaruHina lovers drooling over what they think ambiguous panels mean.

There are still quite a few mangas to go so to claim anything is offical is just ignorant.

Naruto 615 well technically, hinata slapped naruto sense back at him and then caressed his cheek, then reminded him of the "Nindo way"

Guess the author is trying to hint a possible romantic relationship between them as the mange is drawing to a close.
