On second thought, I suppose it's all gravy at this point-- FOX has already made a boatload of money from selling advertising for the original airings, plus the sales 0f 200,000+ DVD box sets. It just seemed odd at first, since there was a lot of hubbub about how Firefly cost so much (roughly $1.5 million per episode) to produce, which is why Sci Fi couldn't pick it up as another original series, like they did with Stargate SG-1 after Showtime dumped it.
