$80 is a bit much for star wars in my opinion. We tried a Star Wars marathon a year ago, and it was such a painful experience that we only got through the the first of the originals. 1-3 just have such terrible actors, and 4-6 are just dated beyond help. And now with the BD release you can see too much detail, and it makes the originals look very bad. Great story though, I just cannot wait for them to be redone with a better director/cast some time in the future far far away...
Anywho, back on topic; As many remember during the BD/HDDVD war we had Morgan Freeman touting his streaming web service, as well as Netflix with it's beginnings of a streaming service, and the question in the back of our minds was "will BD/HDDVD be the last physical media release?" And it is looking more and more that way.
Also, the jump from VHS to DVD was nothing short of ground breaking, and became cheap very quickly, as well as there being a fairly strong economy with a bright outlook at the time. Also theaters were seedy gross places infested with pimple ridden teenagers. Besides, there were no other options available.
Theaters are still infested with teenagers, but they (the teens and the facilities) tend to be much cleaner, and the overall theater experience is much improved as they compete with the home theater experience. Plus you have DVD which still looks OK on a 720p screen, especially when you have a good up-scaler. Plus there are various streaming services such as Netflix, Hulu, Youtube, and the almighty torrent. BD simply has a ton of competition, and the rumors of the high end moving to 2K and 4K in the next few years doesn't help either.
