There are 8 men and 8 women (16 total) from the list of 31 names previously spoiled by Redmond a couple months ago, plus 4 new. Process of elimination, though, means Mike and Alexis have now been definitely cut from that list, short of any last-minute casting changes.
So the 4 new people are:
2 people from S33 - 1 man, 1 woman (will remain unspoiled)
1 mystery male pre-juror from post-HvV (Brad Culpepper* heavily speculated due to Second Chance shortlist... but would love for someone more random like Bill Posley -- he can get some Colton redemption!)
1 two-timer female who has been part of the jury (Ciera highly speculated, could be Abi, or Kass but they aren't as keen)
The remaining 8 men/8 women (all from original Redmond list) are:
Only 1 person from WA -- a woman (Hali or Carolyn) -- this rules out Mike unfortunately,
4 winners - 2 men, 2 women (from Tony, J.T., Earl, Sandra, Natalie A., Sophie, Danni),
2 male pre-jurors (Caleb and Varner are almost guaranteed -- otherwise could include John Cody and/or Peter),
4 men and 4 women who have played twice/three times:
- 1 female is definitely Ciera/Abi/Kass, as above,
- 1 male is almost guaranteed to be Varner, as above,
and that leaves:
- 3 females: Cirie, Andrea and Monica Culpepper* (or only 2 of these, if Sandra is one of the winners),
- 3 males: Malcolm, Ozzy and Penner (or only 2 of these, if J.T. is one of the winners).
(*YMMV if you think it's possible to include Monica and Brad as a lone loved one pair: I wouldn't put it past the show.)
That leaves the following 3-5 post-merge one-time players, all still remaining from that original list:
1 male (if no J.T.) OR 2 males (if including J.T.) from these five: Tai, Jon M., LJ, Troyzan, Marty,
2 females (if no Sandra) OR 3 females (if Sandra) from these six: Aubry, Debbie, Sabrina, Chelsea, Sarah, Natalie B.
