I know of Harmony Gold's claim to own exclusive US distribution rights to all Macross related materials, such as films, toys, and print media. I also know that Japanese courts nullified the original deal Harmony Gold had with the studio that sold them the original licensing agreement based upon the fact that they in fact did not own what they were selling (it was originally a joint Tatsunoko/Nue production).
I am wanting to know if there is any chance of Macross: Delta or F coming stateside, well, ever.
