I believe it is coming back in the fall. Over at SURVIVOR SUCKS, some people have reported seeing/hearing of TA4 contestants doing actual challenges.

I was worried that Tana was going to be fired (if that happened, I would have stopped watching the rest of the season - I've done it before). I'm thinking that the interviews being saved for F3 might have something to do with Verna quitting (which they likely ditn't plan for). They ended up losing two people in one episode. They have to honor their promotional agreements with these companies and HANES might've gotten the shaft if this was an interview episode.
