Of course, with all the buzz currently about Rose of Versailles and Princess Knight, the title I keep hearing about over and over again is Legend of the Galactic Heroes. I have no idea what that title is even about, but with all of the demand for it, I wonder if that might be the next item on the Dark Lord's agenda.
Only if he's a bit megalomaniac...
AFAIK LoGH is a 110 OVA (yes 110 direct to video/LD episodes...) space opera (think Macross, Banner/Crest of the Stars, Star Wars etc.) series with, according to anidb, 2 side story OVA series and 3 movies.
I kind of doubt Rightstuf would want to take on a project the size of UY/Ranma/Naruto/Bleach/etc.
It being a bit "older" (1988-1997) in combination with likely high license price  probably wouldn't do well for the odds of a release (OTOH, Galaxy Express 999 is getting a DVD release and that's also quite old and long... ).
 HLJ still lists 39 items under the "Heldensagen vom Kosmosinsel" German name for it, even though according to AniDB no LoGH has been released after 2000.
I don't think many anime can keep that much merchandise available that long after their release...
