If the rumors of ghost Hayden being in Episode 8 are true, then all chance of an OOT release outside of bonus material in the vein of the '06 DVDs is gone.
At the end of the day the average consumer doesn’t care anyway, and that’s all that matters to Disney/Lucasfilm.
Well, if they want Darth Vader/Anakin in Ep 8, who would they choose to play him other than Hayden? It’s either him, or some new guy we have no connection to.
