Most people feel that the directors cuts of the ST films are superior, and aside from STTMP they are extremely similar to the original versions anyway. Plus the originals were already released (ST VI has a "home video cut"--the theatrical version has never been seen AFAIK, so don't blame the DVD), plus in 2002 no one did multiple cuts. Most likely when they are released again for HD they will have new transfers of both theatrical and directors cut versions.
