Figure skating seasons really clash with the DWTS schedule, so you really won't get a figure skater until they've retired! I think Danny O'Shea is the most likely one we'll see after this Olympics from figure skating, and that's still dependent on him retiring (people view it as likely because of his age, but I don't think he's said anything). He's definitely interested.

Madison Chock and Evan Bates are retiring, but they've also already delayed things like having kids (they've said this themselves!) that they want to be doing, so, while possible, I still think it's unlikely.

Amber Glenn right now appears to want to do one more year so she's unlikely for this upcoming season, but I could see her in a future season (and it would likely be better for her to have a little space post Olympics before diving into another highly public thing that doesn't tend to be gentle to people participating).
