If FreeSpace is to be revived, then the revival will probably not lie in a PC game. With the runaway success of Battlestar Galactica, an imminent Star Trek movie which promises to suck less than anything Star Trek has done in years, and the recent conclusion of Star Wars, the time is ripe for FreeSpace to be developed into other media. Could you imagine a TV series following the exploits of Admiral Wolf, the GTD Galatea, and some other Alpha 1 fighting the Vasudans in the year 2327 or so?
Also, the idea of multimillion-poly Apollos and Orions being processed by render farms makes me salivate.
In my opinon, previous video-game movies and such failed because it's too much video game and not enough movie. And besides, FreeSpace is much less vulnerable to this, being more about the GTA, PVE, GTVA, NTF, and Shivans than Alpha 1 himself. It's easy to make a whole squadron of characters rather than a single Alpha 1, and there's a broad overarching plot into which smaller stories could be injected, Babylon 5 style. Doom isn't so flexible.
