I think I a similar argument can be made for B5 as well...I really hope we get a re-boot or sequel to that show someday.
JMS still talks about it, but his reboot's been in turn-around since 2014. No surprise since WB can't find its butt with both hands. Perceived success of THE EXPANSE or the new TREK might jump start things however.
On the writing side though, JMS has been hit and miss lately, especially in his comics work. But no shortage of good writers he knows.
For cast, we've lost way too many. But Mira Furlan looks almost the same as decades ago, Bill Mumy's around, and Bruce B is always game.
I demand any reboot (if not redoing the whole thing) start during the reign of [spoiler]Emperor Vir[/spoiler].
And that no one mention [spoiler]The Drakh[/spoiler] ever, except as a bad joke.
