It's official: Survivor: Cagayan will feature a final two instead of a final three in the end for the first time in 10 seasons.

Woo Set To 'Burn The Whole Place Down' In Survivor Finale?

CBS has released a new promo for the final episode of Survivor: Cagayan, which is set to air Wednesday, May 21. The promo promises that there will be "three Tribal Councils," essentially confirming that there will be two people voted off in the finale, narrowing down the final four to a final two. The episode will feature the final four Tribal Council, the final three Tribal Council and then the Final Tribal Council, which goes back to the traditional season finales of early Survivor seasons.

While the promo does not explicitly say that there will be a final two, Xfinity reporter Gordon Holmes tweeted Thursday that he has confirmed with host Jeff Probst that it is indeed a final two this season.

Survivor Season 29 Concept Revealed?

This is the first time Survivor is going to go down to the final two since Survivor: Tocantins, season 18.

Enstars previously speculated that Cagayan would have a final two instead of a final three. A vast majority of readers who took the Enstars poll on which they preferred, a final two or a final three, said that they did prefer the final two. A total of 60 percent of people who took the poll said they preferred final two while 22 percent voted final three, and 13 percent said it didn't matter.

As Survivor: Cagayan enters its finale, the four remaining castaways could all make a case for themselves to win the million dollar prize. Kass McQuillen may be considered the least likely to win among the group considering the amount of bridges she's burned in the post-merge, but she has played the game hard and made the biggest move in the game by switching sides. Woo Hwang has not outwardly made anyone angry in the jury and he may be seen as a likable alternative depending who he's up against.

Meanwhile, the two biggest contenders to take the game are likely Spencer Bledsoe and Tony Vlachos. Each has taken different paths to get to the final four. Tony has been in a power position since the merge, finding three Idols over the course of the game. He has made some of the biggest power moves in teh game, voting out alliance members like Jefra Bland and LJ McKanas.

Spencer has been an underdog since the beginning of the game, having been stuck on a losing Brains tribe. After Kass flipped on his alliance after the merge, Spencer has been a target for several votes, but he has managed to stay alive through winning Immunity Challenges and subtly manipulating Tony.

It remains to be seen who will win the $1 million, but if the finale is anything like the first 13 episodes, it is sure to be a memorable and unpredictable conclusion.

Survivor: Cagayan airs its finale Wednesday, May 21 at 8 p.m. on CBS.
