If they've got 25, they can afford to include one or two that the serious wrestling fans would appreciate - Molly would be one of those. Torrie, on the other hand, would be a no-no - her back is in a pretty bad state these days, which is why she quit. Amnd unless Chyna has dropped about 5 stone, I'd be really hoping she ISN'T in there.
Assuming no separate match for the champs, I'd expect:
Melina, Beth, Kelly, Maria, Maryse, Michelle, Natalya, Gail Kim, Jillian, Candace, Rosa, the Bella twins, Alecia, Victoria, Lalya, Katie, Eva, Lita, Trish, Sunny, Jackie Gayda, Molly....
...and Mae Young
That's one spot left, I'm certain I've missed one or two active ones, and you've got Stacey/Sable/Ivory/Cherry as back-up.
