From what I've read from 475 I think that Danzo is going to put up a good fight with Sasuke, I don't believe he will be killed because of what we've seen from Danzo so far is that he will run away from a fight he cannot win, or he'll make a agreement, or Sakura's team will show up an get into a fight with them, and be helping out Danzo because they have no clue that he isn't the Hokage anymore, and if Sakura's team shows up (A) Sasuke will kill them or (B) They will run away (Doubtful tho, since this is Sasuke goal).
