Noone cares about what, exactly? The Blu-ray format itself... or high definition quality?
Blu-ray. I love HDTV and since everything will be converted to HD in the next couple of years there's no backing out of it but Blu-Ray seems to be entirely self defeating. Besides the fact that you have a movie in hi-def, what is the extra space going to be used for? You can fit an entire tv series run on a single Blue-ray disc but every company has money on the mind and would refuse to do this. Why should I sell The Simpsons season 1-10 on a single Blu-Ray for 30$ when I could sell them by individual seasons for 30$? The buyer begins to wonder "Where the hell is all that extra space going?"
At the same time, who's going to buy the entire series run of Seinfeld for 200$ when it comes on 1 or 2 Blu-Ray discs that probably cost, what, 50 cents each to make? The thing I loved about DVD's where the packaging. I like buying box sets because it comes in this wacky case with flip out fold out stuff and it's big and purty to look at. The Indiana Jones boxset (which normally comes in four cases and four DVDs) would most likely fit on a single Blu-Ray and if I bought a tiny, ugly blue case with a single disc in it then man, am I going to feel like someone kicked me in the nuts and stole my wallet.
