If I'm not mistaken Harmony Gold went belly up in the early ninties
late eighties when the Yen became so much more valuable than the dollar.
They (Harmony Gold) had been in the process of putting together an original
animation series continuation of Robotech called Robotech: Sentinels based
off the book series by the same name.  When the yen rose all they're money
was in dollars, so they had barely the cash to cover expenses that they had
amassed so far.  
     The incomplete work was released and sold a few years back.  The final
sequence of the too short tape showed Rick and Lisa finaly married with Lyn
Minmei singing at the wedding.  If you can't find the book series then
Robotech Art Book 3 has a synopses of the plot as it would have played if
it had been finished.
