That is all the information I got from asking around. Believe me, I spent a long time hunting these down at work and trying to get more information on these. This line from Bandai was made before my time and no one at Mattel knew anything about these expect what I just stated.
So, a re-release will have to go through legal mumble jumble between the Mattel and Bandai, as well as Universal...and who ever else was involved in the initial deal. Who knows, the tools may not even exist.
