I realize Survivor 39 has not even aired yet. However, Here is the list of returning winners that will play for the winners only season. This is going to be a good one if you like Survivor. People trying to stand out and make game plays will make this season. It will be strange to see which players will be Identified as people we have to get out now since they could win, since they have all won and are all really solid players.
