I did a google search on some of those pros we mentioned, plus a few others that sprang to mind (not ones that I would care to see again, but just curious what they're up to). I couldn't find anything current on Andrea Hale, but from what I found on Charlotte it looks like she's retired from competitive dancing and is now teaching/training around the world. She and John O'Hurley released a dance instructional DVD last year. And speaking of John, has he ever returned to DWTS? We often see former contestants there but I don't think I've ever seen him. I was thinking of Ashly, and if they go back to having just 6 female pros next season I'm not too sure she'll be back. Unless DWTS decides to copy SCD and have 14 couples total, or if they want to bring over more cross overs from other shows and decide to up the couple count that way. Anyway, I'm betting the ones all one tour (
Lacey, Kym, Cheryl, Edyta, and Karina) will be back. Besides that, they're all familar faces on the show and have their own fan bases. So that would leave one spot.
Anna had expressed interest in returning after one season, and she recently split from her professional dance partner. I can't believe Maks won't be back. People may be more apt to recognize her than Ashly. I hope she doesn't get the short end of the stick again (either of them, because they've both been stuck with crap partners or those with small fan bases). I do wonder if we'll see Tony in the spring. His wife just had their twins in September and to be honest Tony didn't seem like he was enjoying himself much this season. I hope Alec is back 
One celeb I would probably bet money on finally making her appearance next season is Florence Henderson. She's expressed interest for awhile now at coming on, and who hasn't heard of The Brady Bunch? I guess they have to fill that slot, but I do agree, put someone on that is actually going to stand a chance for awhile and who doesn't look completely painful to watch. Jane and Marie started strong I thought but eventually ran out of steam. I hope there's no boy banders next year, but if there is, I guess they'll have to start picking former members of the Backstreet Boys. Only other person from N Sync that would probably be well known would be Justin. And thank god he likely considers himself above doing a show like this. I agree with your point about the athletes; of course some have fallen flat (Monica Seles and Clyde Drexler) but for the most part athletes on this show have done extremely well. I have little doubt Misty/Maks would have been in the final 3. It's doubtful she could come back as early as next season, but I hope in the fall, if she's able, they'll give her another chance. She's dropped plenty of hints in interviews that she wants to return and Maks said nothing would stop him from coming back with her. This season started off on a high note for me when I saw who was cast, but ended up falling flat. Unlike last season, where I had no one I really cared about, this season I had favorites. Unfortuantely they all went out early. I grew to love Warren and Cody, but without Warren this season would have been a complete dud to me. I wish they'd stick to the format used in earlier seasons. Considering it didn't make a huge ratings wave maybe they'll realize the direction they want wasn't a huge success. I wonder how they did in capturing the younger crowd.
I
can't believe Tom lost the reality show host award at the Emmys this year. Probst has nothing on him except a huge ego. I always liked Samantha but after this season? Yeah, I get what everyone complains about. And I agree with your take on Jonathan; he's not my favorite but it'd be nice if he got someone good for a change. I didn't get why the finale was just one long recap of the season. The finales in the past were so much better.
