I'm not too sure about Danzou = Madara. After all, why would Madara "encourage" Sasuke to kill Danzou? Isn't it more likely that Danzou simply has an implanted Sharingan, just like Kakashi, and the bandages are there to help keep it under control as well as hide it?
It's disappointing that Kakashi ALREADY knows of the connection between Naruto and Yondaime. What an anticlimax. I just hope it doesn't get treated like the Kyuubi revelation.
Naruto: "Sakura-chan... I found out who my father was. He was the Yondaime Hokage."
*DRAMATIC PAUSE*
Sakura: "Oh yeah, I know."
Still, I suppose it presents the opportunity for Kakashi to tell Naruto a little about his parents.
Hey, remember the Kyuubi revelation and how big a dud that was?
I agree on Danzou not being Madara yet. The way they are speaking...it doesn't add up. Danzou just said he hadn't been in combat in awhile, but Madara fought Naruto not to long ago and, as you said, why stear Sasuke directly to Danzou on two seperate occasions. Madara's already confessed to helping with the massacre, why hide his role as Danzou while admitting to helping Itachi do the deed?
