The question you should be asking is will Paramount ever release the directors cuts on blu-ray. They seem to be content with just re-releasing the same poor quality transfers of the theatrical cuts in different packaging. The directors cut of The Motion Picture would be a problem too as the new CGI shots were only rendered in SD. I guess that the 50th anniversary in 2016 would be the most obvious date to expect a re-release. Personally I'd prefer to see the movies get new transfers first.
