Let's face it, even if FS3 does get made, by anyone, it will never ever live up to our expectations, how could it? We all have our own idea of how it would look and play, and it would be impossible for it to live up to everyone here's expectations.
The recent increase in interest in the game is as much because of people looking back to the good old days when computer games were original (though there are those that would argue that FS2 was simply the top of a Pyramid based on X-Wing, Wing Commander etc). Maybe that will spark a flame, maybe it won't, but even if it does, the story cannot fulfill everyone's dreams for the finale of the Freespace saga.
