You would think George would want to put out a final version of the OT now (in the next year and a half) before the official continuation happens with Ep7. He can't keep changing it forever. Now is as good a time as any to have the final word on it.
To me, it would be pretty weird to use a dcp of the 04/11 version for this big event in Atlanta, at least for the ticket prices they listed on the website. If it says it's a digital print, that means it's a dcp and not a '97 print.
What did they use for that anniversary screening of Empire with Ford in attendance? Was it a '97 print or a dcp of the '04 version?
The only thing making me think this Atlanta screening might not be a brand new transfer is, well, why would this be the first time anyone sees it? If it were a wide release then sure, it would make perfect sense. But a special screening in Atlanta?
Stranger things have happened, I suppose.
