Many months ago JMS revealed that the first 5 B5 movies would be released in a boxed set, followed by Crusade and a separate release of Legend of the Rangers. The R1 (North American) version of the TV movie set was just released. Warner Bros. had not yet officially announced that it is doing either the Crusade set or the Rangers TV, much less the dates involved. But JMS's post makes it clear that the discs are coming, and I think there is good reason to believe that they'll be released (in R1, at least) by the end of the year. It would make sense for WB to get the last of the B5 discs in time for the holidays this year since S5 and the movie set are out already.
