Star Blazers exist on 16mm film prints and someone could scan that conceivably in HD for a blu ray release, Voyager Entertainment is likely not going to do so especially since they closed their doors in 2012 and are now under the care of the Japanese owners. Tim Eldred being no longer involved even in the capacity as web administrator.
We will not see a uncut Space Battleship Yamato original series in the USA, subtitled or newly English dubbed, or even the cut down versions. We won't see the two cuts of the rebirth film, the live action film or the remake 2199.
Few industries in the USA have suffered as much a Anime has in the great recession.
Always a niche in the culture of the west despite vocal fans. How much has fansubs and illegal downloads hurt the industry, hard to say.
As for Lensman i don't think any EE Smith fans myself included have ever been able to ascertain if the animated tv series/movie was authorized by the smith estate or if the rights are owned by anyone in japan anymore.
The US Cut put together by Streamline pictures and pan and scanned while the japan version was widescreen. Not sure if it was animated 4:3 and matted as a lot of animated films used to do.
A live action film had been proposed by Ron Howard but never went anywhere. Considering how poorly received John Carter was maybe this is good, not sure.
