Generally it's assumed that the blu-ray set will not include the Theatrically shown movies. And since GL and LFL seem to be formulating the Saga6 as the goal not any of the individual films, there will not be any future release of these films as they appeared opening day. Not in theaters, not in the home, nowhere.
So how long will this continue. U.S. Copyright is currently Life of Creator + 70 years. George is 66, let's say he lives to 97 (the SE age/year) that would mean Star Wars goes Public Domain (as long as copyright is not modified) in 2111.
So starting this year for the next 100 years, the Star Wars movies as shown Opening Day will not be shown with LFL consent.
100 years.
yeeha.
