She's a fodder. The villain has to b stronger than the hero until the climax of the story. She's too weak to be a villain.
I vote for the return of kabuto.
I beg to disagree, here.
The Hyuga and Byakugan are based on the elements and history of Taoism - with the portion I want you to pay most attetion to being the concept of Wu-Wei:

To quote:
"As one diminishes doing—here 'doing' means those intentional actions taken to benefit us or actions taken to change the world from its natural state and evolution—one diminishes all those actions committed against the Tao, the already present natural harmony. As such one begins to cultivate Tao, one also becomes more in harmony with Tao; and, according to another great ancient Taoist philosopher Zhuangzi, attains a state of Ming, or 'clear seeing'.[citation needed] It is in the state of Ming[citation needed] that the Taoist is in full harmony with Tao, and 'having arrived at this pointless point of non-action, there is nothing that is left undone.' It is upon achievement of this Chinese equivalent to 'enlightenment' that a sage begins to perform wei wu wei, or 'action without action.' Thus the sage will be able to work in harmony with Tao to accomplish what is needed, and, working in perfect harmony with the Tao, leave no trace of having done it."
Emphasis, my own.
Forget movesets named after deities and enlightened states... that's for raging egomaniacle emos. The Hyuga become the will/force of the natural world, make shit happen, and don't care to take credit for it.
Why else would Kabuto save a dying Hinata Hyuga so whimsically and mysteriously?
Why else would she sacrifice herself to trigger Naruto's encounter with his father? To be -right where she needed to be at just the right moment- to stop him from turning to the "dark side?"
... Hinata's actions during the Chunin exams also triggered a cascade of events surrounding Naruto that ultimately led to a shift in her father's hardened attitude and can be seen to have greatly affected internal Hyuga politics.
She's good - I'll give her credit... but she can't slip below my radar.
That's kind of meant to be silly, above... but also food for thought given the idea.
But, seriously... why the hell did Kabuto cease his killing of Anbu operatives to heal Hinata? Plot mechanic doesn't really work - as she didn't -need- to be dying in the first place. So I'm curious when that's going to come back around into play.
