By the end of this war, I think it's pretty clear Sasuke will not want the Bijuu to stay as they are like modern society's W.O.M.D and are a big determining factor in a village's military strength.
If it ever did come to it, and Naruto's only option would be to either kill the Bijuu or kill Sasuke, who do you think he'd choose?
I think it could go either way. Naruto's whole goal besides being Hokage was bringing Sasuke back. Maybe he will succeed unlike Hashirama or Jiraiya. That's the only reason for sasuke I see; just so he doesn't end up failing like his predecessors.
But I also can't think of a reason to choose the Bijuu over Sasuke either.
