I seriously wonder what happened there. Seems quite serious - a loss of international licensing, perhaps? Or maybe even a problem with the manufacturer. The silence is thunderous...
Possibly a lack of sales in the U.S. (I personally bought the Japanese Blu-Rays with english subtitles as I wanted to see the series as it was released officially - but more because I was concerned Voyager might edit, or give it the 'Star Blazers' treatment. Yes, that got a lot of people into anime and yamato in the late 170ies/early 1980ies; but many of those same fans were a bit annoyed when they saw what the original Japanese version was when compared to what the edited 'Star Blazers' version was - and thus as times have changed and un-americanized foreign entertainment more accepted, might not want to chance another 'americanized' editing job. IE - They won't even buy the first disc to see.)
They did dub the first episode in english (they were shown at some of the major anime cons the year 2199 was first out); and I'm certain it was done to see if they could interest some cable network (the Cartoon Network or maybe SyFy who for a very short period actually aired the 1978 dubbed 'Star Blazers' episodes -- but I have a feeling part of the pitch called for the channel to help pay for further english dubbing; and that may have been a deal breaker with all the other already dubbed anime Funimation has - which seems to be the majority of the anime of Cartoon Network.)
It is interesting to note that Funimation got the rights to, and did do a full English language dub of the 2010 live action 'Space Battleship Yamato' feature film (they also include an English Subtitle track) -- which I saw and managed to pick up last year on Blu-Ray at Best Buy, So, it's interesting that Voyager seems to only have exclusive rights to the anime versions of SBY.
And people here may flame me, but had Funimation gotten the anime version for SBY:2199; we'd probably have an english dubbed version available, and it probably would have been on Cartoon Network's TOONAMI block by now (for better or worse)
Still it's said that their isn't an easier way for U.S. fans who'd still like to have the series to get it; and I hope I'm wrong and Voyager starts making its Blu-rays available again.
I ALSO hope the Japanese continue with the SBY retelling and they do a full 26 episode series of the 'Comet Empire' after the film in the 2199 vien. Time will tell; but I hope they do an announcement one way or the other soon after the release of the film.
