Meh. I don't feel optimistic about it at all.
I hope she has something up her sleeve, something... on par with the boys so she's not just blowing a lot of hot air, but I doubt it and if she did that would probably feel unrealistic and overdone.
Even if she's mastered all of Tsunade's techniques - which I assume she has in order to break the rules of a med-nin and fight on the front line - I still don't see that as something that could keep up with Naruto or Sasuke.
Which isn't entirely Sakura's fault really... if you think about it. To keep up with the Nine Tails Jinchuriki and a Uchiha with EMS is a bit of a tall order. She has no blood limit or tailed beast - she doesn't belong to a clan (so far as we know) so a lot of what she has is down to her intelligence, chakra control, Tsunade's teachings and her determination to stop being a burden.
... but throughout Part II she's been somewhat, lacking. She makes a great med-nin, true. But a front line fighter like Naruto and Sasuke? Not so much.
If she ends up pulling out something ridiculous like Wood Release I might break something.
