It's doubtful for the time being. Danzo is Acting Hokage because Tsunade is in a coma, but it sounds like Danzo will become the Rokudaime. In chapters where Tsunade was about to become Godaime, however, the decision was made by the Jounin in Konoha after the council put forward a suggestion. We don't really know what the Jounin in Konoha think of Danzo, but it's possible that Danzo will become the Sixth.
If Danzo isn't chosen, there is a possibility that Kakashi will become the Rokudaime. There was also a menton in the latest chapter of a villager/ninja who said something along the lines of 'Naruto is amazing, he should be the Hokage!' but whether that is foreshadowing or just a random little remark is unknown as of yet.
