I believe we will get a part 3.Naruto or Sasuke will not become hokage soon.I believe tsunade will still be alive which will make her still be hokage or if Tsunade die due to reviveing the other kages or an incident in part 3 then Kakashi will be the hokage since the elders wanted him to fit this position.As a result Naruto ,Sasuke and Sakura will be the next legendary senin like Jiraya ,Tsunade and Orichimaru.
