Predictions: Sasuke and Danzou fight for five chapters. Sasuke wins with a new killer Sharingan hax technqiue (hell, he could very well end up stealing two spare eyes from Danzou's arm, hence giving him a permanent mangakeyou sharingan). Danzou is thrown out the manga like Kisame was and readers are left wondering why the heck Kishimoto decided to put this character in the series in the first place. At any rate, as others have alluded to, this is bad news for NaruSaku in the sense that we won't be getting any nods towards it unless until January (IMO). Still, it's been a pretty good year for the pairing, so such is not that bad in retrospect.
I don't know about 5 chapters, in fact, I don't know if he will even start this fight this year. I'm starting to wonder if Kishi will have next week dealing with all the other characters and like the last panel be about Sasuke and Danzo starting their fight. I really hope it doesn't last 5 chapters, that would be too much Sasuke, I really miss Naruto lol
