I hope this is in the correct place. I'm sure you all know about the DYRL Superposeables by now. I wanted to know why this was okay, so I asked Tommy Yune in the Robotech.com chat room.

<Ginrai> Tommy, is there an official reason for why DYRL Superposeables are okay now?
<TommyBack> gr-yeah, we finally got around to properly getting the license
<TommyBack> it was something HG didn't pursue before
<Ginrai> Tommy, can you tell me if the rights came directly from Big West or if it was from whoever had the video rights tied up in Clash of the Bionoids/Super Spacefortress Macross?
<TommyBack> gr - no big mess like that, though I won't get into it until AX04 remember, the simplest explanation is often the correct one
Interesting.
