As of 9/18/2013, there is no release scheduled in this calendar year.
If you call Disney Studios contact line 800 723 4763 (hit 1 for english and 0 for operator), they will record your request. I asked for "unaltered original star wars trilogy". They asked if I meant 1-6, and I said "just 4, 5, and 6".
There is also the contact us form, but it was broken at the time I tried. http://www.disneystudioshelp.com/ContactUs
Time to rally the troops! "All wings report in"
