Actor Gary Jones (Sergeant Walter Harriman) revealed that Stargate: Continuum will be released on DVD later than anticipated, a representative of Stargate SG-1 Solutions reported yesterday.

Jones, who moderated the SG-1 panel at this year's San Diego Comic Con event, took a brief question from the floor concerning the DVD release dates. He reportedly stated that Stargate: The Ark of Truth was coming to DVD shelves in the Spring of next year, while Stargate: Continuum was slated for a DVD release sometime in the Fall.

Solutions also reports a FOX Home Entertainment representative stated "the delay was to allow for exceptional computer graphics for the visual effects and an extensive marketing campaign."

Already three shuttle buses at Comic Con have been branded to advertise the upcoming DVDs, as well as the fourth season of Stargate Atlantis.

Beware of spoilers for the fourth season of Stargate Atlantis in the story below!

As Samantha Carter (Amanda Tapping) takes over command of the Stargate Atlantis expedition, she will have to do more than just worry about the constant expressions of lust from Rodney McKay (David Hewlett).

The fourth season of Atlantis will feature a new alien race with technology far beyond that of the expedition, as well as a storyline centered around the real-life pregnancy of Rachel Luttrell ("Teyla Emmagan").

"We had a story in development where [Teyla] would be out in the woods with Jewel [Staite], and it was a fairly violent episode," said Paul Mullie, executive producer of Atlantis, during Tuesday's SCI FI Channel digital media tour in Vancouver, B.C. "We were writing the story when [Luttrell] came in and told us she was pregnant. We were too far down the road to change it, so we decided that, 'Oh well, she doesn't know she's pregnant in this story.' It was the story which in the end she finds out."

Producers decided to write Luttrell's pregnancy into the show, although they would not give details on exactly how the pregnancy would be incorporated. Luttrell, who was showing physical signs of her pregnancy at the press event, said jokingly that her pregnancy was a way to make sure that the producers further developed her character in the fourth season.

"This was to ensure more of a character arc," Luttrell said. Mullie, however, added that they had wanted to incorporate a strong story arc for Teyla in the fourth season, and her pregnancy made it that much easier to find a way to do it.

Outside of making babies, the Atlantis expedition is going to make contact with its first race that is actually far more technologically advanced than just about every other culture they have faced. Because cultures in the galaxy tend to not advance very far society-wise because of cullings by the Wraith, cultures that are more advanced than those manning Atlantis have been few and far between.

However, the Travelers, as they are called, are expected to make an appearance early in the fourth season ("Travelers").

"One of the things that Atlantis kind of lacked that [Stargate SG-1] had were technologically advanced races," said executive producer Joseph Mallozzi. "We created this race called the Travelers. They are nomads, traveling on ships and establishing a civilization. They are very rustic, and have a very cool look."

The Travellers are expected to show up again sometime after the fourth episode during the upcoming season, Mallozzi said.

Since the announcement of SG-1's two movie storylines this past January (story), fans have been trading hypotheses behind a core question: What is the Ark of Truth?

Besides the fact that it is the title for the first story to emerge from SG-1 post-cancellation (Stargate: The Ark of Truth), the Ark of Truth denotes a valuable device which may turn the tide against the ongoing war with the Ori. Stargate Executive Producer Robert C. Cooper gave GateWorld the inside scoop about this very important artifact.

"I find it a truly fascinating centerpiece," Cooper said of the Ark itself. "It's a device that essentially is a -- I don't want to say 'brain-washing' -- but it can be used to convince you of the truth."

"Say you believe something," he said, "and I think that what you believe is wrong. So I program the Ark a certain way and open it and show you the inside, and now you'll believe the truth -- or believe what I've programmed."

Essentially, the Ark is a device capable of brain-washing Priors, Ori proselytizers who bend worshippers to their will.

"One of the Alteran scientists invented this device and said, 'Look, we can avoid any kind of war by just using this on them and brain-washing them.' And the rest of the Alterans said, 'No, that's just wrong. Philosophically and morally it's wrong.'"

Instead, the Alterans departed from what is now known as the Ori galaxy, eventually making their way to the Milky Way. "They had a ship, they had weapons, they could have killed the Ori (the people, human beings the Ori). [But] they left. And they came to our galaxy. And history happened the way the series has told us."

Dr. Daniel Jackson now believes the Ark may still exist. But in search of the device, the team will have to ask themselves the same question the Alterans once faced: "'Is this morally wrong?' Even if we do find it, should we use it? Is it the right thing to do to convince the Ori followers that their beliefs are wrong?'

"Because," Cooper admitted, "it's not necessarily wrong to believe in something ... what's wrong is to murder somebody because they don't believe the way you do. So we're not convincing them not to kill people -- we're actually changing what they believe, if this all works out in the way we think it might."

Some fans have argued that Stargate technologies like the Ark, the Prior inhibitor and the Kull disruptor have lent to "quick-fix" solutions in stories. However, executive producer Brad Wright has iterated that finding technology to defeat Earth's enemies has been a staple of the series from the very beginning (interview), and is in fact integrated into SG-1's standing orders.

Stargate: The Ark of Truth will do what Stargate does best: point a mirror back on its audience. "Philosophically," Cooper told GateWorld, "it's a very interesting moral argument, which I think is very current and a very contemporary idea."

Expect The Ark of Truth to hit store shelves as early as this fall.
