Ah, the good old days, when Optimus Prime actually still looked like a semi truck in his robot mode...
Here is an April 21 article by Emily Claire Afan of KidScreen. The first DVD set was released in mid-June, with the second, more robust, version still forthcoming or just hitting the shelves now:
"Transformers fans will be able to get their DVD fix soon, as Hasbro and Shout! Factory have entered production on The Transformers: The Complete First Season 25th Anniversary Edition DVD box set, slated for a June 16 release.
"The set (SRP US$29.99) features all eps from season one of the original 1980s series, with remastered audio, bonus content and is packaged with a collectible Autobots magnet.
"Also in development is the 16-DVD The Transformers: 25th Anniversary "Matrix of Leadership" Edition Collector's Set (SRP US$29.99), with more than 38 hours of content, including the entire original animated G1 series, extras and special collectible book, slated for a mid-July release."
