LAST EDITED ON 04-14-13 AT 10:59 AM (EST)In the heat shown (l to r) we see Brenda (yellow), Malcom (red), Eddie (green), Erik (purple) and it doesn't matter who is on the yellow platform but I suspect it is Reynold as from the picture, it looks like they have gotten off to a good start. It will be one of the Kewl Boy alliance who wins this heat and two will move on: Malcom, Eddie will move on from this heat (and/or Reynold - if he is on the yellow platform).
The second heat must be: Andrea (because we see she does move on), Dawn, Sherri, Phillip and Cochran and/or possibly Reynold).
My guess is that either Eddie, Reynold or Malcom wins immunity this week. Rupert (the strongest) easily won it on Pearl Islands.
Also, fwiw, according to the Press release, "an accident threatens one survivor's ability to stay in the game," it doesn't appear to have happened pre-immunity challenge as all survivors are present and accounted for and smiling on the platform.
