Probably time for the BBC to start developing a new chat show to air in the Spring once he's wrapped up, with the hope it one day succeeds him in the slot for most of the year.

I think the most recent chat show I've seen on the BBC is Chris & Rosie Ramsey. I'm not sure in its current form its ready to take over.

It's worth noting though that Graham Norton's chat show was quite different when it began on BBC Two.
