Please do not get your hopes up that this will happen.

The climax of the Con is more likely to be the keynote speaker announcing that Adam from Girls will indeed go shirtless in Episode VII!!!!!!!

Edit: For a little perspective, look at this note regarding the mono soundtrack included in the new Criterion release of A Hard Day's Night. For a real restoration/recreation of the OT, this same painstaking process would need to be done not just for the soundtrack, but for the entire film and optical effects. There's no way anyone is doing this in the throes of EPISODE VII hyperventilation

I don't see why a separate team couldn't do it.
