Other than a television reunion special (slated for a November release), and some possible Firefly comic projects in the works, I haven't been able to find a whole lot in the way of actual Firefly news. Granted this is an aging series, and whatever we get from here on out is pretty much icing on an already delicious cake.
Here's what little media footage I've been able to compile. Hopefully, someone will post the reunion panel, and preferably before November! During the Firefly press conference Nathan does a James T. Kirk impersonation that's destined to become a internet sensation.
A speechless Joss. . . well almost speechless.
Alan Tudyk interview (This video has like 40 minutes of blank recording. I changed the embed code so that it should begin playback right about the spot the interview actually starts - if for some reason that doesn't work skip to time 1:22.00). Pay no attention to the drunk Cap at 1:18:00 - he's an imposter.
