The 33rd season of Survivor hasn't even aired yet but some fans already know details about season 34.

*Casting and tribe spoilers for Survivor season 34 ahead*

Survivor superfans are already aware that season 34 will feature all returning players, thanks to Inside Survivor's Martin Holmes, a.k.a. Redmond. According to Holmes' inside sources, season 34 will feature winners like Sandra Diaz-Twine, Tony Vlachos and J.T. Thomas, favorites like Malcolm Freberg, Cirie Fields and Tai Trang and more.

Holmes has also learned that the season will be titled Survivor: Game Changers - The Mamanuca Islands. As for the tribe names and divisions, Holmes just posted a new report revealing all the details.

The Mana tribe, whose representatives will wear red/blood orange, includes Sandra, Tony, Malcolm, Aubry Bracco, Caleb Reynolds, Ciera Eastin, Hali Ford, Jeff Varner, Troyzan Robertson and the season 33 female (go here to see exactly who).

The Nuku tribe, wearing blue, consists of Cirie, J.T., Tai, Andrea Boehlke, Brad Culpepper, Debbie Wanner, Ozzy Lusth, Sarah Lacina, Sierra Dawn Thomas and the season 33 male (check the above link).

Much like the tribe dynamic in Survivor: Cambodia - Second Chance, the divisions appear to be random, though there are a few notable splits based on past seasons. For example, castaways who were associated in past seasons but are on different tribes this time around include Andrea and Malcolm, Brad and Ciera, Caleb and Tai, Sarah and Tony, and Hali and Sierra.

Filming for Survivor: Game Changers is currently underway, though the end date is fast approaching. According to True Dork Times' calendar, Day 39 will be July 14, so as of today there are only a few castaways left in the game.

Survivor: Game Changers: The Mamanuca Islands is expected to premiere next February on CBS.

Meanwhile, Survivor returns for season 33, titled Survivor: Millennials vs. Gen X, on Wednesday, Sept. 21 at 8 p.m. ET/PT on CBS.
