I'm not sure that this is the only time we will ever see the O-OT/OUT on DVD. Not counting a potential HD-DVD/blu-ray release, Lucasfilm hasn't exactly stuck by its past statements. Lucas swore at one point that Star Wars would never be released in any home video format because the only way to see it is in theatres. Then there is the famous "one last time" promotion for the 'Faces' release before the SEs came about. And I'm sure there have been others. Don't get too excited by a statement saying never again. It doesn't mean anything.
