Amazon MGM Studios has announced that the Stargate franchise is getting a new series. Even more importantly, MGM has tapped long time franchise writer and producer Martin Gero as creator and showrunner for the new series. The goal isn't to reinvent the wheel but do more with what was proven to work for over a decade.
The intent is a continuation of the universe and not a reboot. What that will look like remains to be seen. The Stargate franchise got its start as a movie but really took off with Stargate SG-1 which exponentially grew the universe and its concepts along with additional series Stargate:Atlantis and Stargate Universe. No ETA on the series, I would estimate at least two years out so late 2027, maybe 2028 since this is just the announcement as no indication that a writer's room has even been assembled much less casting started.
I strongly recommend giving the original series a watch and the behind the scenes footage that comes with the disc sets is very much worth a viewing as collectively its almost a breakdown on how to make a show on time and on budget while still being able to tell the stories they wanted to tell.
