Re: Sakura Haruno's possible character development.
There is a lot of foreshadowing in Naruto, there is also a very direct pattern Kishimoto has been known to follow and while you say it's unlikely Sakura can surpass Tsunade because there is no proof, you can't deny that it's been stated before in the manga not only by Kakashi, but also Chiyo that Sakura has the potential to do it.

But, this thread is highlighting Sakura's potential and possible development. One of the many themes in Naruto is that the younger generation surpass the old generation. This has actually happened in a lot of cases already, we're seeing Naruto's development as well as Sasuke's development and already at such a young age they rival if not outmatch their previous sensei. So it's not completely untrue to say Sakura can surpass Tsunade when there's already been so many hints towards it being a possibility.
