Why is Five bringing back Superstars?

Anyone know why Five is bringing back classic 70s sports show Superstars?

Not only has BBC1 tried it and failed – perhaps because they had Johnny Vaughn as the main host and he’s best at armchair comedy – they’re bringing it back and messing around with the format. This time it’s going to be teams (three men and one woman in each).

Anyone going to watch it? Anyone got any ideas about why they’re bringing it back?
