I have a feeling that in order to not dishonor Lucas that a fully restored OUT will not happen at least not soon. This is probably on part of both Fox respecting an old deal and Kathleen Kennedy at Lucasfilm who is a personal friend of Lucas. The other threads on this subject mention that Fox has distribution rights anyway and Disney owns the property so they'd have to come to some sort of deal to even get that ball rolling.

All of the attention will be on the new films anyway so they want everyone thinking about that new timeline and era with Rebels and not so concentrated on the OT.
