Just say, some newbie (note the little n - he's a sensible newbie) arrived, claiming to be a former (or current I guess) V staff member, with the story for Freespace 3. DaveB backs him up, so there's no question of its authenticity, and he wants to make a fan project to complete Vs trilogy.
The story is fairly detailed, with complete mission descriptions and the like, but the project would require a lot of work, dozens of mods, cutscenes, source changes etc.
So, hypotetically... would we get it done? FSU, the closest recent example, hasn't technically dies but went very quickly from a lot of excitement to a lot less. We've also begun to realize that most of our own promising projects are dying due to lack of manpower - would you really be willing to take time away from the projects you're working on (or running, in the case of many talented individuals in the community) to work for an effectively unknown newbie? Would the lure of a proper end to the series, one that you might not even agree with, be enough to get the coders to lay aside their personal aims, and move in the directions that the FS3 story requires? And do we even have enough people and enough motivation to take on such a massive project any more?
Hypothetically.
