There likely will not be an official release of the Star Wars trilogy on home video until the copyrights expire and we get a good public domain release.
But who here has time to wait for the end of western civilization?
https://en.wikipedia.org/wiki/Public_domain_film :
Due to the U.S. Copyright Term Extension Act, no more films will automatically enter public domain in the United States until January 1, 2019, when the copyright will expire on films released in 1923 (and in 2020 films from 1924, and so on).
Isn’t Disney the king of keeping IP’s private though? Mickey Mouse…
