I think kakashi will tsunade will end up becoming one of the village elders part of the leaf council having kakashi become hokage because let's face it we know it's naruto's goal and everything but he isn't ready for it
Kakashi will get it naruto will become jonin without doing the chunin exams ( I feel like it be retarded for him to do the chunin exams now) and then kakashi will turn down and let naruto become hokage
