The first bit of news is that a movie set in the Babylon 5 universe begins production in April in the United Kingdom. The Memory of Shadows deals with the technology of the ancient and extinct Shadow race being unleashed upon the galaxy by an unknown force. More info can be found here at Lurker’s Guide to Babylon 5. But the chances of the movie actually being made are still slim, judging by Keep B5 Alive.
The more solid and upbeat news is that Ben Browder of Farscape fame is joining the cast of Stargate SG-1.
