Maybe (this my idea[my ideas are not always coherent, I warn you]) HG has brainwashed them into thinking, that if threy let Macross in the U.S and there derivities, it would cause product confusion, leading to less money being spent on there (HG) prouducts.Hence less of a fanbase= no more Robotech. I mean honestly. If you picked up a MP from toynami, then a 1/48 Yamato, which one would you buy (assuming that a US Yamato would be lower in price, even if it wasn't I'd still for a 1/48)? I know I'd toss the MP away.
