During last night's telecast of the 'Survivor: Samoa' reunion (full recap here), CBS premiered a teaser for the upcoming 20th cycle of the show, confirming that it would be a second "All-Star" edition after all. Officially titled 'Survivor: Heroes vs. Villains,' the clip showcased virtually every prominent player who's ever been on the show -- certainly more than could fit within the 20 contestant limit.

Fans of the show have been working for months, tracking contestants' Twitter and MySpace accounts, interviewing crew members and possibly even digging through the trash to find out who will actually be cast for next season. In the process, some have wondered whether 'Samoa' runner-up Russell Hantz would be able to appear, the same way Rupert Boneham went straight from 'Pearl Islands' to 'All-Stars.'
