Here's a preview of Brian Stelter's interview with Deborah Norville, the host of the syndicated newsmagazine "Inside Edition," about big changes in morning and late-night TV. In the video clip, Norville reacts to David Letterman's retirement announcement.

"Lord knows, he deserves it," she says. "I don't know if he'll be off television forever. I can see him doing some kind of quirky something when he wants to, as he wants to. I'm sure a lot of other TV entities would be thrilled to bring him into the fold. It will be Dave's choice to make."

Watch the full interview Sunday at 11 a.m. Eastern time on CNN.
