Well, as Obi Wan once said, that greatly depends on your point of view. You can't buy them on the new format, but the old formats won't last much longer. (Future tv sets may not even have the old analog video inputs.)
We would all love to pay George for a super deluxe Blu Ray set that has everything but the kitchen sink, but he doesn't want to to that. What's a fan of the old version to do that isn't technically illegal if they want to keep watching what they already paid for?
