I think sony bought the rights to both transformers and g.i. joe series from Rhino, and I would suspect that transformers would be rereleased around the time the new movie would be appearing in stores. I don't know if the DiC episodes were ever acquired by either company, so seeing anything after season 2 is not too likely as of yet. There are 27 episodes on Season 1 volume 1 and 28 episodes on season 1 volume 2. For about $50, they seemed reasonable at the time, and are close to the price that Thundercats and He-Man have been recently released at. If it is humanly possible, I would say check the local video game stores, like gamestop or ebgames for a more reasonable price. I found season 1 volume 2 for around $35.
