Seems to me that they're setting Castiel up as the "king of Heaven." Especially with this episode.
I sincerely doubt either of the Winchesters would take the mantle of the king of Hell, nor would either really want to be the king of Heaven either.
I'm thinking it would be more of a burden they accept rather than a desired promotion-- a responsibility they feel they must accept in order to change the rules of Heaven and Hell.
