TL/TR: New series is not a reboot, but a continuation of the SG1/SGA/SGU TV universe.
Brad Wright, writer & produces on Stargate TV series:
"I just want everybody to know that MGM and I are working on something. It’s just too early to talk about. And it’s partly too early because there is a pandemic going on. And that’s kind of ground a few things to a halt.
But we are working on something. It’s very exciting. It’s something that we have been talking about for a while now. And I love it — I’m excited to have the possibility of making it someday soon. Or someday, period!
I’ll say this much: It exists in the universe that you already know. It’s not a reboot, it’s not a completely new thing. It’s a continuation. And I’ll leave it at that. I’m not allowed to say anything more! I’m sworn to secrecy."
