If Mizukage vs Sasuke occurs, the fight won't be concluded much like in the Raikage match up. Sasuke just wants to finish off Danzo.
Raikage, Mizukage, Deidara, & Orochimaru - Sasuke's opponents are formidable. Presently, he is 2 -0 and one, not yet concluded. I can't wait for the Raikage vs Sasuke in anime and watching it on television.
Why do they have to fight? I kinda like the Mizukage, she retains her feminine charm despite being the strongest Ninja in her village. The good news is, we will see what her techniques are.
Naruto manga issue 45 is second in New York Times manga list (Sept 13 - 19). I missed every weeks of the anime already.
