If I had to guess, I'd say he made that either

a) just because, in which case it's likely that he'll continue that trend, or

b) because he thought the series was going to get cancelled, and wanted some sort of dramatic ending to everything he'd been working on.

Either way, the way the fans have received Epitaph One should show the people at Fox that it's something worth doing. Of course, they'd have to air the first one before they could show the second one. Maybe they could do it back to back. Combine that with heavy advertising, and I'm sure they'd get something out of it.

But when has Fox ever been intelligent enough to do something that cool. I mean, you remember Firefly, right?
