Sorry for continuing the derailment of the thread, but given that I feel lucasfilm/Disney/fox would be idiots to not accept legacy, my guess would be this:
For the 40th anniversary they release both a boxed set as well as individual releases of legacy paired with their own (probably rushed and sub-par) restorations of empire and Jedi. It’ll be like the Indiana jones the complete adventures set where they had all the films, but only raiders had the brand new restoration.
