Despite strong support on LEGO CUUSOO, the Macross project could not happen for one big reason. While only one project ended up making the cut on LEGO Ideas a long running dispute over who owns the rights to the Macross franchise in the United States has stymied the franchises development outside of Japan and especially in North America. While Macross was developed in Japan, its international distribution rights were sold to American company Harmony Gold, which is best known for releasing the Robotech adaption of the anime in the United States.
Harmony Gold has proved hostile towards the importation of Macross related products from Japan and still claims ownership of the international license, despite ownership technically belonging to Japanese firms Studio Nue and Big West. These owners of the Macross franchise have not challenged Harmony Gold putting things in a state of status quo ante bellum. Thus, partially for this reason, LEGO shelved the idea of a Macross set due to simply too many legal hurdles to jump through or rights and licensing holders to deal with. LEGO likely will not just release a Macross set in the market where it would be easiest to do so (Japan), and ignore the rest of the world. But one can hope, that some day soon, intellectual property disputes will be a thing of past and LEGO and Macross fans everywhere can get their hands on a set of a VF-1_Valkyrie.
