with out a doubt we will see it. No idea when my guess would be probably before the new movies come out to help build hype.
A day later, I'm leaning towards this would be the time Disney would do it. They are known for the "limited time to get it then back to the vault it goes" gimmick.
Reason I thought about this was I was tempted to get someone a gift of the entire sage but noticed with 9 blu rays in that thing why couldn't they add the theatrical releases? So I probably will get the prequel set for the gift and wait until Disney does their gimmick for the original trilogy.
