I'm genuinely curious, what did they butcher? As book to series adaptations go, I felt this one was fairly close.

Hand-wave it with "anti-aging drugs" as referenced in the books, give the cast a little bit of a makeover, and call it five to ten years!

I've kept tabs on some of the showrunners, writers, etc. on Twitter, and there's the occasional "we can't say anything, yet."

Which currently seems like they're trying to shop it around to see if anyone will pick it up and continue the story, and may be in some form of talks here or there to figure it out. Personally, I believe it's just a lot of kicking the tires.

On paper, it's got plenty going for it: Excited fanbase, still an in-demand show on Prime Video despite not having a new episode in almost a year, workable on a SyFy budget, some pretty big plot hooks to continue after S6, etc. And not for nothing, there's a TellTale game coming out to flesh out Drummer's backstory with Cara Gee reprising her role via VO. I'd hope that counts for some sort of general market interest/desire by Alcon Entertainment et al to keep The Expanse top of mind.

Here's hoping that somewhere in a few years they get locked in with someone ready to pick it up!
