And in that announcement Michael Davies will still be the executive producer as well. I have a hunch that they're waiting to see what Fox does with Call Me Kat- if it gets canned, I wouldn't be shocked to see Mayim get the full-time gig if she wants it...
Yesterday, I watched J! for the first time in awhile, and I'm under the impression they are going toward naming Mayim the permanent successor based on her availability, based on the intros I've seen. Johnny Gilbert has introduced Mayim as "the host of Jeopardy!" while I noticed he said last night, "and now, hosting Jeopardy!, Ken Jennings!"
When Ken was "guest-hosting," he sat at the lecturn, ala Alex, and all the other guest-hosts stood at the podium. Ken is standing at the podium now, but I've wondered, as well as hoped, will they ever have the host located at the big board for Final Jeopardy! They had Alex seated at his podium primarily because of his foot injury for good long time.
