UPDATE: More background here. The Supreme Council of Antiquities rejected the proposed successor, but don't want Hawass either. In fact, they want to get rid of the Ministerial position and return to it being under a scholarly body (themselves). (And Hawass hasn't posted to his website since July 14.)
A publication called The Art Newspaper is reporting that Zahi Hawass has returned to his office because the nomination of his successor was withdrawn. He's still presumably on the way out, but has a reprieve if this report, which quotes Hawass himself, is to be believed. The man appears to have more lives than a cat.
