I think the reason a lot of people are reacting so much is that for the majority of part 2, the focus was all NaruxSaku and little to 0 mention of Hinata. Then all of a sudden Hinata gets 2 moments of spotlight and some people blow everything out of proportion by saying things like there have been no naruxsaku moments or Sakura does not love Naruto despite Kishi's interview. To me, it looks like NaruxSaku still has a Big lead over NaruxHina and Hinata is not as much of a threat as people think she is.
Well there will always be the ones who will exaggerate everything and consider a closed deal the entire hand holding thing between Naruto and Hinata.
But then again the NS shippers are also Sakura fans and if we make a small review of what was discussed this past few days there are some who consider Sakura's involvement to be on an emotional side while others want to see Sakura kick some ass.
Problem is that during this entire War arc Sakura didn't really do anything in both departments, her only moments of note were the ones in chapter 540 ( where she thought of only Sasuke albeit not in a good light) the Zetsu-Neji clone and the small monologue she had in her mind when all the army decided to reinforce Naruto's position.
The War arc lasted in Real life for a pretty long time and yet only this moments, small compared to the others around her.
And there's another problem. The way Naruto progressed she currently doesn't really have anything to bring to the table for him.
- She tried to fix the POAL with Naruto and determine him to stop looking for Sasuke but Naruto was adamant in his quest to redeem Sasuke.
- She also failed when trying to take matters in her own hands.
Even on the love or support department she lacked a lot. Especially because Naruto as a Jinchuuriki needed love to control the negative emotions of Kurama yet....
- When Naruto went 8 tails Minato stepped in and supressed the Kyuubi.
- Naruto supressed his own darkness all by himself
- Afterwards Naruto went to obtain Kurama's power this time saved by Kushina
- And lastly he managed to also let Kurama let go of all his hatred
Yet there is only one thing she can do in this arc, albeit a small one, but pretty significant and that is for her not to die. Now the 616-617 chapters would give reason for some to downplay an eventual death for her but one can not compare the death of a comrade to the death of a loved one. Also the fact that Naruto resembles Obito in many ways and Obito's fall into madness was caused by the death of loved one, I don't really see how someone would be able to help Naruto out of any feelings he will experience if Sakura would die.
