As per PrettyKitty's post above, two people are supposedly out. They may not stay that way. But for now, the rumor has it as a pair off the ranch under their own power, and the season will continue without them. Note that given the initial reason for their leaving, this was pretty much self-defeating -- they opened two slots, and how long would you expect them to remain that way?

This would ultimately break down to one simple fact: they have to show the departees. They can lie about what happened, they can edit it until the gone ones are shown attempting to strangle Bob, they can remove an entire week from the schedule, but they cannot completely ignore it. A temporary strike where everyone eventually came back could be edited into oblivion. With actual quitters, someone will have to say something. It's too late to recut the show and make a pair of contestants vanish from the entire season.

I expect that something to be 'Wah wah, look at the babies who couldn't take a simple twist.'
