Though there was word not too long ago that it was being considered for a rebirth, I'm not sure if "Celebrity Sweepstakes" was/could be considered for a prime-time spot.
Though it has all the desirable traits for a prime-time show (celebs, audience participation, high stakes potentials,...) my biggest concern is that they would take the "horse race" speed that we know and love from the original and turn it into a molasses race -- doing only doing a minimal amount of questions within the 30- or 60-minute span and wasting more time with celebrity interactions, like Hip Hop Squares.
