I can't be the only one waiting for a revival jutsu (Chiyo's Jutsu) and watch Sakura sacrifice her life for Naruto (or Sasuke).
I realize that this jutsu was only known by Chiyo but if I remember right she was brought back. (I can't recall if she's been sealed yet, if so please remind me.) So she might teach Sakura the technique or Sakura already has a similar technique.
She obviously is pretty useless in a fight if it's stronger than a Zetsu clone...But she is a very skilled medical ninja and I think she'll be dead by the end of the series.
I would imagine if Sasuke dies, Sakura will have to die as well. With how the series has been molded I would assume that Naruto and Hinata will actually pair up. Sakura I feel will die with Sasuke but will give her life for something important.
Only time will tell, and I hope she actually plays a big part other than crying all the time.
