I'm not an expert on the subject, but I believe the reason this will never get released in the US is because Harmony Gold (the Robotech people) are falsely claiming ownership of anything related to Macross in the US, even though they were only entitled to the original TV series.
For some reason, Japan and the US are in the same Blu-ray region. So I was going to import this, but now I am not.
The censorship has been confirmed now. A friend of mine in Japan with the censored Blu-ray and the uncensored DVDs is talking about doing a fanedit.
