Volume 2

I couldn't find anything official, but I'm not too hopeful. Volume 1 was released a year and half ago and it's doubtful they would wait that long between sets. I assume it didn't meet Shout! Factory sales goals and so plans for a Volume 2 set were cancelled. I've also given up hope on a continuation of "Silverhawks" as the first set came out a year and change ago.

Here is what I found on it's wiki entry

recently, the only available English language DVD in Region 1 was Escape from the Garden of Evil (4 episodes) from NCircle Entertainment.[3] However, Shout! Factory announced that a DVD release of the complete series was in production.[4] Volume 1, containing episodes 1-33 spread over four discs, was released in the US on March 25 2008 (however, some Best Buy stores had put it out a week early). This represents half of the episodes produced. Volume 2 containing the remaining episodes will be released depending on sales success of Volume 1.[5]

After the release of the first volume on DVD by Shout! Factory, Amazon.com listed "Jayce and The Wheeled Warriors #2" as due for release on Region 1 DVD on the 1st July, 2008. Later on in that year the listing was updated to cancelled. However, users on the Shout! Factory forum state that the release on Amazon.com was not the second volume by Shout! Factory but was another 4 episode release by NCircle Entertainment.[6][7]
