Well, being one of the three working on it, I can give you a pretty reliable answer - it kind of petered out... If that's how you spell it.
For myself, I procrastinate a lot, and considering how huge we wanted the game to be, it involved far too much writing for one person (i.e. me). And it won't come back on-line any time soon, as I don't have the energy or time.
I still have the work I did, though - if anyone's interested, and they clear it with Nick&Chris Bischoff, I'd be happy to mail it to them.
