I have a theory...

I was just on another board where someone called The Inside a mini-series and suggested since it was probably heading to DVD maybe Tim should just produce 13 episode mini series. It got me thinking, how's Prison Break get more than 1 season? Surely Reunion with it's format of each episode representing a different year can't go more than 1 season. Could FOX already be using this 13 episode mini-series format? Am I on an island here? Is this crazy talk?
