20th season of survivor

So you read Jackie's review of last night's Survivor finale, and the show had their usual preview of the next season of the show (which starts February 11 so there's hardly any wait at all) which will be a "Heroes & Villains" edition, former players coming back for another try at the $1 million.

Not sure if we can make out who is on the show from the clip below. For the villains, I'm sure we'll see Johnny Fairplay, but Richard Hatch was probably in jail when they started to film it. For Heroes, maybe Tina and Colby?
