Will Kakashi be Hokage before naruto?

No, Danzo is the 6th

Danzo, the head of Root ANBU, was annointed sixth Hokage by the Hidden Leaf's elders.

Extra comments:

Not Naruto. I'm pretty sure Naruto WILL be a Hokage, just not the sixth. Sorry to disappoint you (not really, because it's Masashi Kishimoto you should be disappointed in) but Naruto, for one, is not even a Chuunin. He's still Genin. Second, Danzo is a lot older and wiser than Naruto, not to mention is head of Root. Naruto just doesn't seem like the good choice to be Hokage, as he lacks in both patience and temperance. Well, in everyone else's eyes.
