I'm hopeful, mostly because like many have said, it would be a huge promotion for the new movie coming out.

I also think we would have heard definitively by now if they weren't ever putting it out. Lucas was always super vocal about wanting the originals to be unavailable. From "the special editions, those are the versions I want out there" to "grow up, they're my movies, not yours," Lucas (nor Lucasfilm) never hid the fact that they weren't putting out the originals in any acceptable form.

Disney, on the other hand, haven't said a word. At this point, I feel we would have heard, whether it was as simple "we are not putting out the original versions" or as complicated as a contractual agreement with Lucas to never put out the originals. Clearly Fox is not a real barrier here (as many have speculated), as they were able to work together for the stupid digital release, so as far as I am aware, there is literally nothing stopping them.

I'm hoping we will know something by the end of this weekend. It might be weird announcing something basically a week after the digital release, but I imagine any physical OOT release would be targeting a crowd that mostly had no interest in the digital release. Who knows though.
