There are just five castaways left in "Survivor: Worlds Apart", and tonight we will finally find out which collar the winner wears.

This season, which is the 30th season of the hit show, had people who were either blue collar, white collar or no collar.

At first, host and producer Jeff Probst wasn't too confident. "We weren't really sure how it was going to go, if it was all going to mesh together or if there was going to be separation," he told Enetertainment Tonight. "And there was so much separation. For us that was really powerful-to remind us to keep trusting our instincts and to keep trying things."

Three of the remaining contestants are blue collar, according to Us Weekly. "When the game started the blue collars all said somebody from this tribe is going to win," Probst said.

Probst decided to share what he personally thought about each of the remaining contestants: Rodney, Carolyn, Will, Mike and Sierra.

The game show host thinks Rodney has a chance to win if he can stop all his complaining, but added that Carolyn is a threat.

"Rodney's game I think has gotten a little lost in the complaining," Probst says about the 24-year-old contractor. "But he's such a hustler that if he can get to the end I could see him talking his way to the million bucks because that's what Rodney does in life. He talks you into things."

Carolyn, on the other hand, is the oldest finalist, and "is a definite threat to win." 

"I think Carolyn is good enough with her speech and her words that she could win this game and I think Carolyn knows that," Probst admitted. "I think she's sitting right now thinking 'I've got a real shot at this.'"

YouTube Sensation Will Sims II doesn't seem like he'll rise to the top, though. "I don't think Will could win," the producer confessed. "I think Will had a shot because my experience with Will was, he was actually a really nice guy. Super likable." But after Sims made an extremely personal comment to previous contestant, Shirin, he lost people. But that's exactly what Probst loves about this show. "You create the rules. 'Survivor' is the player, the players are 'Survivor.'"

According to Probst, the other two finalists, Mike and Sierra, need to make big moves if they want to make it all the way to the end. If they can accomplish that, they have a shot at winning.

With this season coming to an end, Probst already has his mind on the next one. Season 31 will have quite the twist, and is going to be all about second chances.

Season 31 will have 32 of the shows previous players. Each of these returning players are ones that viewers believe deserve another shot at this game, and it's up to the fans to choose who they get to watch compete again.

Tune in to CBS tonight to see who the ultimate survivor is and to see who the returning players will be on next season's "Survivor."
