I still think we need to read (and listen) between the lines here regarding the OUT and future releases, though, and I am convinced we will see it again soon. Even that trailer is careful to point out more than a few times, "For a Limited time only, own EACH movie of the Star Wars Trilogy INDIVIDUALLY on DVD." I feel that is how Lucas will get around the whole OUT being limtied thing in the future, because they will be bundled together, or without the SE, or with the PT...
Also, "As a special added VALUE bonus, the original theatrical version from 1977, 1980 and 1983." Value usually equals "just good enough for the money." Nothing will stop a better version for more money, and again, yet another way for Lucas to get around the whole "You will never see the OUT like this again" thing.
