I'm just curious as to think who will become the 5th hokage?

I've narrowed it down to:

Ero Sennin- He's damned powerful, but seems to want to stay away from things...
Kakashi- Also powerful, has high standards.
Hyuuga Clan Leader Guy- Powerful, used to leadership, and can see long distances.


if you can't tell by now, I have no idea, but I think that the next hokage has already been introduced, and if he hasn't then that'd be cheap.
