Oh, man. What kind of tangent did I get this thread into?
To get things back on topic, let me just say that the prospect of a 4k blu-ray format hitting the market by the end of 2015 makes me wonder how Disney might handle an OOT release leading up to Ep7 (if they choose to do so).
It might actually be a good idea to get a blu-ray release out of the way by September. They'd make a killing on the 1080p blu-ray just in time for a new format to show up. If they wait any longer, there will be more people who will hold off until they can just buy it in 4k. Look at what happened to dvd sales once hd dvd and blu-ray showed up.
The timing of the GOUT's release is worth considering in the context of looming new formats...
