Multiple DVD covers are spewing out of the Stargate Continuum project at the moment.
Gateworld was the first to post details of the cover, and ran with the following image.
Shortly afterwards, TVShowsonDVD.com found another piece of cover art, apparently also official.
Can’t help but prefer the first one guys, just looks more professional and finished. Time will tell which eventually will be used.
Also, if you’re interested, about a fortnight ago there was yet another small preview of the covert artwork released, again completely different, for the DVD.
