How the hell is Hinata going to get a power up instead of sakura?
Between the 2 sakura is more relevant and would most likely get some sort of power up. The last time we saw hinata, she was passed out on the ground with the rest of the alliance. (who are irrelevant btw).
This kaguya-hinata connection is so stupid. They only share the byakugan and are female. That's it! Why would hinata get a power up over sakura or kakashi (team 7)?
If you haven't noticed the only characters getting any attention right now are team 7, gaara, gai, madara and obito.
Hinata is not as important as sakura, even if she ends up with naruto she still will never be the main heroine. She has hardly had any panel time in the entire manga nor has she had any interaction with kakashi, sasuke and other major characters. Thus she is not a better female heroine. And this is coming from a hinata fan. She is a wonderful girl but she is a secondary character.
