Someone on the Shout board has confirmation of a street date from Timeless. They will be releasing S2 and S3 at once in the same package, which means it goes from "one and done" to completed in one fell swoop!
"Timeless Media Group, working in conjunction with Universal Studios, will be releasing seasons 2 and 3 of Alias Smith and Jones in an official commercial DVD set. The entire set will be on 6 DVDs and will run more than 29 hours. The cost will be $69.98 and the street date for the release is June 8, 2010. The 90-minute second season opener, "The Day They Hanged Kid Curry," (which did not air on Starz Encore Westerns in 2005-2007) will be included in the release. This information was obtained from a Project Coordinator for Timeless Media Group."
