simply put sasukes chakra is different know that he has the 3rd doujutsu, he is somewhat more powerful, and in 3 years will prolly be on the same lvl as itachi, pffft doubt it. but he will prolly kill kabuto or something and gain the mangekyou sharingan.
uh as for sakura it was just a matter of ACTUALLY DOIN SOMETHIN FOR ONC, finally but this plot was kinda predictable, i hope after the kakashi saga there will be some scense of naruto and them training,and growing.
but i just want to see LOTS more kisame wanna see him kill a few ninja's. just totall massacure, akatsuki go out and just kill a bunch of random peoples.
