Reading this, it's not hard to understand how film companies like Lucasfilm can easily get away with releasing a heavily DVNR'd blu-ray. Though it's not as bad as Predator of course.
I don't think this was about demand (because the one that exists is a clear minority), specially when Episode III has added grain. I believe it was for the 3D conversion, where the grain gets in the way.
