I've only seen reports that Skinner has been confirmed. I've seen it posted about being a panel show but no report or confirmation about it.
I thought Dara O Briain or even Sean Lock could be good choices. They've both hosted similar shows in the past. I guess Skinner is also a good choice though and the others may have other comitments.
The Sean Locke one about the best and worst TV (it turned out to be all rubbish) was surprisingly good. Most were very good. But apart from me I think the viewing figures would be very low.
