Stargate Atlantis on Blu-Ray
Stargate Atlantis: The Complete Series will be released on Blu-Ray on July 26 in the US. It will be a 20 disc set. For more information see TV Shows On DVD. No news on a Stargate SG-1 box set.
Stargate Universe and Stargate movies shelved indefinitely.
As you have probably heard, it's the end of the line for the Stargate franchise for now. All options have been exhausted for the continuation of Stargate Universe and Stargate movies. We probably won't be seeing any new Stargate any time soon.
