"Stargate: The Ark of Truth": As SG-1 searches for an Ancient artifact which they hope can defeat the armies of the Ori, they learn more Ori ships are about to be sent through the supergate to launch a final assault on Earth. Daniel discovers that the artifact, the Ark of Truth, may be in the Ori home galaxy, and SG-1 embarks aboard the Odyssey to find it, and pre-empt the attack. The IOA has a plan of their own and SG-1 ends up in a distant galaxy fighting two powerful enemies.
"Stargate: Continuum": While SG-1 attends the execution of Ba'al, the last of the goa'uld system lords, Teal'c and Vala inexplicably disappear into thin air. Carter, Daniel and Mitchell race back to a world where history has been changed: the Stargate program has been erased from the timeline. As they try to convince the authorities what's happened, a fleet of goa'uld motherships arrives in orbit, led by Ba'al, his queen, Katesh, (Vala) and his first prime, Teal'c. SG-1 must find the Stargate and set things right before the world is enslaved by the goa'uld.
Still no word if Sam will end up the one and only "Sir!""
