Deliberate creative decisions.
Yeah, he claims that these were creative decisions he originally intended but he either: Didn't have the technology to do it back then, Didn't have the time/money to do it at the time.
George Lucas could have just as easily inserted Darth Vader saying "Nooooooo!" with 1983 technology as he could have with 2010/2011 technology when he was making the Blu-rays.
This is him changing his mind after all these years and I won't stand for it. Most films get respectable DVD/Blu-ray releases, even unpopular films. Star Wars is probably the most popular film in history and we keep getting these sub-par releases of the films.
