Here's something I'll grant Lucas:
LFL doesn't exactly have as many films in its library as any of the major Hollywood studios. In fact, it really only has a handful of titles people would regard as classic. Take away all the royalties LFL receives from all those hundreds of other companies and you're left with only a handful of products they can make a direct profit off of.
Had Star Wars remained the property of 20th Century Fox, right now we'd likely be reading a press release for a Blade Runner treatment and not the PT+SE box set. From a totally realistic, business-minded perspective, I can't really say I blame Lucas for milking the OT the way he has. It would be nice if he'd stop lying about it, "ohhh, they don't exist anymore .... well, I'll put them out, but won't spend a dime remastering them .... it would be way too expensive to remaster the OOT for blu-ray," but I get it, 3 of the few dozen films he owns the rights to just happen to be the most popular movies ever made and he's gotta keep milking them because not only does he know he can, he kinda needs to.
It's a cruel irony, but it's the truth.
