Rock Star: Next Season -- I'm trying to think of bands now. Obviously, Van Halen would be a fabulous train wreck. Double the ratings if David Lee Roth auditioned for his old job back. Who else?
Or, if Mark Burnett wants to secure several seasons of insanity at once, they could change the format and do Rock Band: Guns N Roses. Each season Axl would search for a new band member.
By the time he had a whole band together, he'd be ready to fire them again. They could probably get 10 seasons out of that.
And Chinese Democracy still wouldn't be done.
