He's going to go after Danzo and whatshit. Then everybody will get into one big fight again with Hawk holding back Naruto and his group. Sasuke will kill Danzo, and then Naruto will catch up and they'll fight. Naruto will be better than him, but they'll both be exhausted. Then Kabuto/ Orochimaru shows up and is like "ah, the both of you are here eh? But only one of you interests me." Naruto's like "NOOOOO!!!" Sasuke gets taken over by the new OrochiKabuto, whatever the hell he is, and Naruto goes back to crying about not being able to save Sasuke. From there the story is about trying to bring Sasuke back and shit. Not unlike it already was.
