I'll respect your perspective on Sakura, but there's only one thing i'm against with her. Even if she became quite strong (that is of course, Ninjutsu-ly speaking) her small female body frame couldn't take too many (if any) really stong blows...it would just throw her outta the match too fast. Unless they give Sakura some absolutely amazing and mind blowing techniques later, with unmatched wit and thought out precision's, she won't be much of a challenge. We'll have to wait and see.
