That too.

It could be that he's there to announce his final version of the SE (from the Reliance 4k job we've been hearing about) and, to counter the "who %#*^ing cares" response that would follow from the comic con audience, Disney's also gonna announce a blu-ray set that includes the remastered originals.

I'm not holding my breath for this to actually happen, but it's one big, giant "could happen" in my mind.

Yeah it's a bit of a stretch. That being said I don't feel that Lucas's desire to see the OOT limited to 4:3 letterbox extended beyond his own tenure at Lucasfilm. I can't see him being opposed to other people releasing it now that he has sold the company, or at least not opposed enough to try and do anything about it.
