Nobody and no theater in their right mind projects a film from a dvd on the big screen. This is where Lucas is just totally off base.
Blu Ray does not come close to film resolution. Much less dvd.
Adopting HD video while wise in terms of cost especially when you are financing your own films the art is actually taking a step back. The star wars film made in the seventies resolves so much more image physically than episode III its not even funny.
The negatives are rotting in a vault someplace because he has now convinced himself analog is evil and digital is better. When those master prints and negatives are the only archival source of the movies. He can claim all he wants that a old HD scan done years ago is archival, but i am not buying it.
Only recently has the state of the art gotten there. And they for years did not have the tech or the power available to fully capture vistavison photography.
Years ago Lucas said i believe in a book where interviewed by ebert that the 70mm prints of the originals with the six track mag track were the definitive presentation of the films. Even talking about how the best prints were the technicolor ones and they would be good for all time. He claimed the films were preserved. Only years later when the 20th anniversary was on the horizon for star wars did they find the negatives were not handled or stored properly and the stock used eastman kodak was completely faded.
As for the Indy blu rays if raiders is the same as the Hd broadcast with the single added cgi shot i'm not buying it even years down the line when i have an HDTV and blu ray player. Especially if the masters look like utter shit because of the heavy dnr applied by Lowry, you can count me out unless a proper restoration and new scan is carried out. Any half assing it like Paramount recently did with star trek and no money for Lucas ever until he does right by the films.
Most importantly that carries over to the original star wars trilogy needing a godfather level restoration. Only something like that and only the original versions will i ever buy.
There are also consequently no film prints of the 2004 versions and i don't believe the cgi on the special edition or the 2oo4 are even film level resolution. The original effects don't stick out like a sore thumb because they were not rendered digital video done on a computer they were real special effects shot physically and optically composited.
