Roddenberry's Star Trek was " above all, a critique of Robert Heinlein"

I try to look at the glass being half-full and appreciate what we did get rather than the half-empty part of the glass where the studio screwed over JMS but knowing these facts make it difficult. I haven’t kept up with the latest B5 rumors. Has there been any progress on revisiting B5 as a movie or TV miniseries? The B5 universe is such a rich playground (like Roddenberry’s Star Trek) I’d love to see it return in some form, even a reboot given that the original actors (those still living) are getting a bit up in years. Maybe the suits at WB were actually working for the Shadows.
