I wouldn't mind if widescreen was included in addition to the original aspect ratio, but I'd much prefer a whole list of things before widescreen was a priority.
And, certainly those shows were released on DVD in their native aspect ratio -- those were SD releases. But if they were released to Blu-Ray, would they be the cropped versions? 1.33:1 shows I've seen on Blu-Ray so far have been pillar-boxed, not cropped. These include Star Trek
, The Twilight Zone
, The Prisoner
, and Space: 1999
