Not just one of the best Sci-Fi series of all time, but I think it was also instrumental in recognizing that it is possible to reward an audience for wanting to really invest in a show by giving it a story arc that remains consistent across 5 seasons and 110 episodes.
Like you, I own the DVD Box set. I would love to own the High Definition versions on BluRay. I won't be buying or renting via streaming as my domestic internet just isn't reliable enough for that. If it were just me, I'd be tempted to move... but apparently if I suggest that again my wife will divorce me - and that would be bad.
With "The Expanse" [another excellent sci-fi show], it took significantly longer for the BluRay/DVD copies of Season 4 to be released after Amazon bought the show from SyFy than it did when SyFy were streaming it themselves. My theory was that Amazon wanted to nudge as many people as possible to subscribe to Amazon Prime to see the new season before they sent it to print on Bluray and DVD. I have no idea, however, whether there would be any appetite to offer a BluRay boxed set of a show that was first broadcast between 1994 and 1998, because I guess it would all come down to perceived market interest.
Then again, when you look at some of the utter rubbish being re-mastered for 4K...
I hope they do offer BluRay copies. It would be nice to see them maybe film a tribute or two for those who have passed "beyond the rim" - Andreas Katsulas, Richard Biggs, Jerry Doyle, Jeff Conaway, Michael O'Hare, Stephen Furst, and now Mira Furlan.
