Since BW is trying to fight for it's ownership of Macross derivatives, they simply COULDN'T let this get released with HG's name on it. Letting it slip by would weaken thier legal stance considerably. Since we're 100% certain they don't want HG involved in the sequels they had no hand in, is this really surprising? It's kind of disappointing for the fans, but BW is doing what they feel they must. We have no say in it, and we can't assume to know how BW should run their business.
I'm not going to sit here and pretend to know the situation between HG, BW, and TokyoPop as BoK has in his rambling. He has no inside information, yet blames BW already. Even if BW did pull the plug, do we even know for certain that BW was involved in this release at all? Perhaps TokyoPop tried to bypass them completely and go through HG directly. We simply don't know.
