I should have posted the following a few weeks ago… 
The above YouTube-uploaded video is the opening theme for CBS's 
Survivor: Heroes vs. Healers vs. Hustlers. 
The credits for the listed cast are in this order:
• Heroes (blue)—JP, Katrina, Chrissy, Ben, Ashley, Alan
• Healers (yellow)—Roark, Desi, Cole, Mike, Jessica, Joe
• Hustlers (red)—Ryan, Lauren, Simone, Patrick, Ali, Devon
My quick assessment:
The ones who have potential (game intelligence to go far):
• Heroes (blue)—Chrissy, Ben, Ashley
• Healers (yellow)—Roark, Desi, Mike, Joe
• Hustlers (red)—Ryan, Lauren, Ali
The younger players generally have the advantage. There has been only one player age 50 or older who won 
Survivor. That is Bob Crowley, from Maine, who won 
Gabon in Fall 2008. On the list of players past 40, with potential, are Chrissy and Mike. But, I think they are smart enough to go quite far. (I also think it of Ben and Lauren, both in the mid-30s.) We will have to see how it shakes out. Between the three hot guys cited by other forum members—Heroes' JP, Healers' Cole, and Hustlers' Devon—I think only one of them [Devon] has the potential to reach far. It appears the other two don't have individual mind for going after the game. But, I did want to list three originals from each of those likewise original tribes. I added another one (just prior to submitting) but will not say who. This person is from the Healers tribe. The fact is: As of four episodes (effective 10.18.2017 broadcast), no original player has lost out from the Healers tribe. Two each are gone from Heroes and Hustlers. And that has me already wondering if the winner of 
Survivor: Heroes vs. Healers vs. Hustlers will be a player originating from Healers.
