I wanted to touch on a couple of things.
Kishi isn't done with Hinata's feelings yet.
This is probably going to be an unpopular opinion, but I'm pretty certain that Hinata and her feelings for Naruto aren't done yet. We're still going to see more of them future chapters.
633 was the perfect opportunity to have Hinata switch to using Neji as the source of her motivation and confidence, to try for strength in order to honor his memory and sacrifice, to work hard in order to be a worthy clan leader. This would have been a natural and believable segway to have Hinata move forward from her romantic idolization of Naruto, to grow into her own character instead of constantly using Naruto as a crutch. And yet, Kishi didn't take that out.
He instead chose to have Hinata think once of Neji, brought up the handholding again through her thoughts, including Naruto squeezing her hand this time, and for her to think such a serious thought as "I want to be by Naruto-kun's side forever."
We dismissed Hinata's thoughts in 540 and 573. It was the same one-sided drivel we've always seen from her, so we didn't think anything of it. But those moments, in hindsight, were clearly building up to 614 and 615. Whose to say that Hinata's thoughts now are not also leading up to something bigger? Why bring up the handholding twice after it happened (volume cover and 633), and in such a short amount of time, especially if Kishi was done with Hinata's feelings and wasn't planning to go anywhere with them? 633 just doesn't make any sense in that context. Thus, Kishi definitely has plans yet for those feelings.
BUT on the other hand,
its just as obvious that he hasn't had Naruto show any romantic feelings for Hinata at all. If NaruHina was the route he was planning to go down, then 631 makes no sense. 615 would have been the perfect opportunity to really start developing Naruto looking at Hinata in a different, more romantic light. To start dropping hints that he's considering her as more than a friend.
But instead, he sets it up so that Minato sees Sakura with Naruto, leading him to ask Naruto the question that tells the readers he still has romantic feelings for Sakura, which in turn leads to him confirming that the pairing hint in Kushina's words way back when was always intended to be Sakura.
PLUS its undeniable that when looking only at the side who doesn't reciprocate (i.e. Naruto > HInata, Sakura > Naruto, and Sasuke > Sakura) that Sakura is really the only one that KIshi has hinted at actually reciprocating.
Sakura has blushed over Naruto multple times, some in obviously romantic contexts (while flirting with him at their reunion in part 2, hugging him at the summit, and then in part one thinking "what is this feeling?") - Naruto has only ever blushed over Hinata when she gave him her proud failure speech and told him she thought that he was a really strong person, which isn't romantic in context, as its the exact same blush Naruto had when Jiraiya told him that Naruto reminded him of Minato - Sasuke blushed over Sakura once when she was jumping all over him during the first bell test (after running across just his head sticking out of the ground and thinking he was dead), but again, the context wasn't indicative of romance, given how he treated her immediately afterwards (and Kishi was really prone to blushes that early in part one).
Sakura has flirted with Naruto (at their reunion by asking him if she looked more womanly, and then by offering to feed him ramen). Neither Naruto or Sasuke have ever flirted with Hinata or Sakura respectively.
Sasuke has never initiated positive physical contact with Sakura. Sakura initiated the hug, which had the blushing crowd behind it and the little girl with the classis "how romantic" pose and expression. Further, the only other person Sakura has hugged is Sasuke, whom she is canonically in love with. Naruto initiated the handhold, but didn't give her any particularly special or emotional expression. The onlookers didn't indicate the hand hold came off as romantic. He also held Shikamaru's hand the very next chapter. The hand holding got much more focus than Sakura's hug did, by appearing on a volume cover and then by being brought up again in Hinata's thoughts in addition to being built on (by adding Naruto squeezing her hand), but there was nothing romantic in it from Naruto's side, nor did anything else in the scene indicate that it even came off as such.
Third party comments is what really seals the deal. Shikamaru said "even Sakura" couldn't change Sasuke's mind - it shows some significance that Sakura had for Sasuke, but again, nothing necessarily romantic. For Naruto we only ever got Kiba's comment, which is a joke compared to the other two's comments (especially since it was ignored completely). For Sakura, we get Sai talking about her being gentle with Naruto, and speeches about the strength of her feelings and cut off sentences to build suspence.
Logically, I think the most likely outcome from this is that Hinata's feelings are going to play some part in future chapters, but it won't lead to her feelings being reciprocated. Again, if anyone is going to have a change of heart, Sakura is the only one with an actual foundation in the manga to do so, both in regards to her feelings for Naruto AND her feelings for Sasuke.
If any of the rookies should fight with Naruto and Sasuke, it should be Rock Lee and even he isn't strong enough. She has yet to show the twin lion + 64 fists combination, but since we're only dealing with Gods now I don't see her fighting any soon. Or maybe she'll get hurt.
