It's not official from SciFi just yet, but it sounds like Stargate SG-1 is getting cancelled. Multichannel news reports that they heard the show was cancelled on the eve of the 200th episode. Gateworld reports that it received confirmation of it from one of their sources. (Oh, and it sounds like Stargate Atlantis was renewed.)

Considering that it's on its tenth season, I'm not surprised about the news. If we take the 200th episode seriously, I'm betting the producers are looking to make a movie. Take everything you see/hear/read/channel with a grain of salt, nothing's official just yet.

Looks like SciFi has confirmed the cancellation (and the renewal of Atlantis). Thanks to Fred for the link]
