I think this is great...

Dalton: So how is the announcement of who actually makes the cast going to work?
Jeff: Here’s how this is going to work—you vote up until the first hour of the finale when we’re live. We’re in Los Angeles, we kick off the show, we start running that last episode. And for an hour, the polls are still open.

Dalton: Up until 9 p.m. Eastern.
Jeff: Then they close. Then we finish this season, we have a reunion show, and in the audience will be the 32 people with their suitcases ready to go. And at the end of the reunion show, we will do a live reveal of the new cast and they will literally leave the studio, get on a bus, and start heading out. And what I love about these guys is they know that—they know that it’s going to be in front of everybody, and you’re either in or you’re out. And that speaks to what I talked about: that motivation. They don’t care that they might be embarrassed by not getting the votes, because they want it bad enough that they’re willing to risk that. That’s a ballsy move, to sit in an audience on a live television show and know that you may be told yes or you may be told no. And if you’re told no, it really is being voted out. The audience of your favorite show just told you, “We don’t want to see you, sorry.”
