I'm starting to doubt there will be a third movie. MGM's taking too long to get it's act together. Actors move on, get older, sets get torn down, props get auctioned off, and people loose interest. Sometimes, a movie can be made years after the show ended with the same actors from the show. Star Trek: The Motion Picture came out ten years after the show was cancelled. The X Files: I Want to Believe came out six years after the show ended. However, does SG-1 have that kind of mass appeal where people will check out the movie years after the show ended? Continuum came out in July, 2008. It's almost December, 2010; and there's only a script. I'm falling into I don't care territory, because The Ark of Truth and Continuum did a nice job of wrapping up loose ends. Where else is there for SG-1 to go? O'Neill's based in Washington, Carter's got her own ship, Teal'c has probably rejoined the Free Jaffa nation, Hammond died... most of the characters have moved on. It just doesn't feel like there will be a third movie.
