I just don't see why Hinata is THAT important that she would be focused on more than the others just to see her have development.
Maybe it will help to look at it this way. Hinata, more than any other character in the story, represents Naruto's affect on his peers and his village. His optimism, bravery, and dedication to what he believes is right -- despite initially being shunned and branded a loser/idiot -- changes people. Hinata herself said that these qualities in Naruto "saved her" and she always wanted to be by his side because of it.
In my opinion, Hinata is getting panel time right now because this is her resolution. I see the purpose of Neji's sacrifice as twofold. (1) He reinforced Itachi's message to Naruto that he's not an island, and that he's carrying all the hopes and dreams of everyone who dies or is willing to die for him to achieve the Greater Good. (2) He fulfilled his Hyuga destiny, bringing into sharp focus that Hinata has another, greater purpose in life and that she, like Naruto, now carries the responsibility of Neji's hopes and dreams. Neji sacrificed himself as much for Hinata as he did Naruto.
For a long time now there's been this question of how Kishimoto could be so cruel as to break Hinata's heart and not give her Naruto when she's such a nice girl. (Let's just ignore the obvious that this is not her story, and her feelings aren't the focus.) I've wondered that too -- how Kishimoto would resolve Hinata's feelings favorably, since the evidence (starting with Naruto's consistent lack of romantic interest in her) suggests she's not going to end up with Naruto.
The only answer was for Kishi to change Hinata's perception of her own role, and I think that's what we're going to see happen after Neji's death. Neji's sacrifice finally gives Hinata a tangible purpose beyond her crush: a heroic path of her own to pursue as a part of the Hyuga legacy. She now has the means to walk by Naruto's side in the Big Picture sense, and not simply because she has a crush on him.
I see this latest chapter as having great potential to be a win/win. Except for poor Neji.

The only thing that worries me is that kishi will use these opportunities to make Naruto see Hinata in a different light.
In case what I said above doesn't help, consider Naruto's expression in the latest chapter:

Now, remember this from the Pein arc?

After 177 chapters there's no change. Naruto's expression and attitude reflect concern, if not outright panic at Hinata's presence. Why? I think because he knows Hinata is out of her league. I think he worries more about Hinata because, quite frankly, he knows she's insecure, lacks confidence in her skills, and despite her brave intentions simply isn't up to the challenge. The entire basis of their interactions has been Naruto giving her pep talks about her capability; it's no surprise that he would be concerned.
Truthfully, Naruto hasn't been able to accept anyone's help or sacrifice. That's the point. He doesn't want anyone getting hurt or dying because of him. He was mad at Sasuke for saving him during their fight with Haku, he doesn't want Hinata making sacrifices, and he said the same thing to Neji -- "Why would you go this far for me...?! Sacrificing your life..." (No doubt he would've had the same reaction to Sakura protecting him and Sasuke in the Forest of Death if he hadn't been unconscious at the time.)
It's kind of telling that about Neji Naruto says, "Why... Not in a place like this...!! You're the Hyuga's..." What's the end of that sentence? Genius? Strongest person? Only hope? No matter what it is, it tells you that he doesn't consider Hinata to be on the same level.
Contrast that to his confidence in Sakura. He knows Sakura, knows what she's capable of handling. He trusts her. This is something he simply doesn't share with Hinata, and when taken with Naruto's stated love for Sakura... well, there's just not enough time left in the story for Hinata to realistically overcome the bond Naruto shares with Sakura or his feelings for her.
Besides, I still think there's a very good chance we will see Obito test Naruto's resolve by threatening Sakura in some way. If that happens, I think Naruto's heart will be laid bare for the world to see. Then there will be a resolution of some kind with Sasuke, and what will remain is Sakura's choice.
Just my opinion.
