Hinata definitely needs a resolution. At one point, when her panel time was rare and less impactful, I'd probably be saying the opposite. Hinata's smile during the NS hug seemed like a conclusion for her. Then 573/615 happens. Kishimoto has made her more important, to the point that she now
needs a resolution. The fandom expects it.
I truly doubt Naruto rejected her already off-panel. Might be wrong, but IMO that's not the Naruto I know. I always assumed that Naruto purposely avoided responding, but not because he wasn't sure of how he feels. When Sakura confessed to him, it was very clear he
knew he loved Sakura. That's why he got angry and harsh in it (
I wrote a whole post about the confession somehere in the debate thread. 
). Naruto is a naturally nice guy and while he can be blunt, Hinata's like fragile glass. He has
no idea how hurt she'd be if he just flat-out rejected her. This might seem like a d*ck move of Naruto, but if I turn out to be right, I totally see this as in character and understandable. I honestly think the closest Naruto leaned toward a rejection was when he saved Hinata from Zetsu, thanking her for saving him and that she was strong. The NH fans think differently, but I've always interpreted that as Naruto subtly hinting he doesn't return her feelings without actually coming out with it.
Unfortunately, Hinata didn't see it like that. 573 showed a burst in confidence, but not directed at the right source. She's now even more sure of her feelings and wants to express it to Naruto. In a way, she's stepping up. Look at how she violated Naruto's personal space by caressing his check during her whole damn speech (Loved the way I typed that lol). No doubt, Hinata's getting more determined and confident in her affections. She's oblivious of Naruto's unreciporcated feelings, much like her fanbase is. They really are an echo of each other, aren't they?
I think the best course of action right now is not for Hinata to get outright
rejected by Naruto verbally (Gawd, those NaruHina fans will hate him forever. *shudder*). It's better for her to realize it herself that Naruto's in love with Sakura and will always love her. She can go up to him and smile genuinely, saying "Naruto-kun, I understand. I'll always be grateful for how you changed me, but I know I should live for myself now." Hinata can direct her full attention to the heiress role. That is the perfect resolution to her character. And honestly, I'd prefer it if she gets
no new love interest. I mean, the girl's entire character revolves so completely around love for so long, it'd be a major hallmark for her to actually not need it anymore.
Completely agree...almost!
Yes there has to be a specific, unequivocal resolution. Kishimoto has now invested a lot more into her character. There has to be a collateral resolving of her storyline. Not as big as S/S/N but not as small as say Kiba or Shino.
But I just don't think Kishimoto is going to make Naruto verbally let her down, simply because Kishimoto shies away from making Naruto do those bad things. If Naruto were to do that — personally, verbally reject her — then a good chunk of the fans would not like him.
Kishimoto has let Naruto sidestep some very prickly situations before (questioning Itachi comes to mind), so I just have a sneaking suspicion he will do it again here.
I don't really know what I want from this. I don't know if I want a resolution at all because I felt there was already one given.
I rather treat this like a band-aid. Quick with as little pain as possible. If you spend too much time on it, you end up making it such a big deal out of something that should be so simple and really I don't want to spend a whole chapter focusing on this when there is so much more important topics to focus on that require even more attention. Let's be frank, there is a lot more important things to show than Hinata getting a love resolution.
Which is why I find it weird people expect more importance from Hinata and why she should get this "attention"
We just spent a chapter focusing on Hinata's love. Out of nowhere. In the middle of a war. At this point, I wouldn't mind a chapter clearing it up, unequivocally. So because there was a 615, I think there needs to be some equally weighted resolution on the back end. Not because
I want it. But because Kishimoto wrote it that way.
And, eh, I'm not really worried about one fandom losing out to another. That were will be disappointment goes without saying. But if Kishimoto builds up the NH fandom only for tension, then drops them without a satifactory resolution of Hinata's character, everybody would be unhappy — NH and NS alike.
And we'll have to disagree on Hinata's resolution — I never felt there was one. Ever. Kishimoto clearly has a plan for her within the manga, and I don't think that plan is finished yet.
