I agree with Sannin29 ^^^ I believe that the sixth Hokage will be Kakashi. After that, who knows? Shikamaru has the brains, sure, but he's a bit too lazy. In my opinion, Naruto will become a wanderer like Jiraiya. I hate to say it but there's a good possibility that after Kakashi, Sakura will become the 7th as Tsunade's understudy.
