That brings me back to the quality control issues. It seemed as though Lucas just greenlit the 2004 releases at the last possible minute in order to make the release window. And so everything, including the digital restoration, color timing, sound mix, etc. were all rushed into production. It didn't help that Lucas likes to change things as they go along, adding new CGI shots, etc. When color timing the film, they probably didn't use a source print as reference and instead asked Lucas what he wanted in each shot. After working on the prequels, he probably saw the opportunity to make the OT look more modern and hence the crazy color timing.

Well that, was then and this is now. Instead of re-releasing the same rushed to the market version four times in a row now, why did't he get back to work and perfect it?
