He has done the equivalent of 'I have no son!'. He has stated again and again that he can't stand them in their original versions.
So as far as he is concerned he hates the way the original films were released with a passion. As far as historical stuff goes, he considers the many many laserdisc, VHS and archived film copies out there more than enough - if he could he go and destroy them too so there was no evidence of the films in the version that he detests so badly.
Sure he changes his mind a lot, but it would take a religious awakening of momentous proportions to change his mind on this one.
If he suddenly had an apoplectic fit and changed hs mind, even financially it would make no sense, the costs to bring the OT as it was to DVD would be extensive, (contrary to popular belief there is no single digitised version of the OT at the ranch, just reams and reams of digitised elements) and how many copies would he sell of a faded Stereo version of the films - I would guess 100,000 copies at an absolute extreme, which isn't worth the effort from a money point of view.
About the only hope of ever seeing it on DVD would be if the AFI decided to digitize the film as a preservation measure and someone got a hold of it and leaked the terrabyte or so of files to someone who would compile it onto DVD and bootleg it.
