J. Michael Straczynski gets his own panel when he does Comic-Con, and he has a following. People fill the room just to hear him talk about whatever he feels like talking about at the moment. He's pretty fun too. And today he very briefly spoke about a new Babylon 5 show.
Straczynski, who of course created the classic sci-fi series, was somewhat cryptic about the state of the franchise. He said until a deal is done he has to be. But he explained that a new series could happen.
Apparently, last year Warner Bros. approached Straczynski about a new distribution system that they were attempting to launch, and they wanted him to produce a new Babylon 5 for that system.

Straczynski, who over the years has dabbled in a variety of spin-offs of the series, said that he didn't want to do anything on the cheap anymore (*cough* The Lost Tales *cough*). So his terms for Warner Bros. were: two to three million dollars per episode, commission a full season and grant him full creative control And they went for it.
But then, months later, this new "distribution system" collapsed.
And yet, Straczynski says that there's still a chance that some kind of show will happen. Again, he can't say much right now, but the implication seems to be that this is a sooner rather than later situation. Will it be a reboot, a sequel, a prequel? Only Londo knows!
