I'm torn. I've barely bought dvds or blu-rays in the past few years because of various reasons, but I am a person who prefers to have a physical copy when possible. In fact, most of my purchases have been Criterion Collection blu-rays during sales. I haven't opened many of them and almost view them as an investment in case they go out of print.

My biggest gripe with blu-ray would be all of Sony's proprietary bullshit. They are a pain in the ass with licensing the codecs. For example, if you buy a blu-ray drive for a computer you also need to buy a license for one of two or three pieces of software that can actually read blu-rays. It's not "open source" like DVD. This is one of the reasons I rooted for HD-DVD - not because HD-DVD was the better format, but because Sony is a horrible, horrible company.

On the other hand I don't see a market for something beyond blu-ray for anybody except the high level enthusiasts an technophiles. If we end up with three formats on the market at the same time, it could be overwhelming for some people.

My guess is BD is the last major disc format. DVDs still sell quite well and people just aren't ready for upgrades to their hardware and discs. Digital is just too easy for most people. I'd love if digital distribution incorporated a method of having a bit more ownership on your digital content. For example, maybe you download a movie you bought and store it on a blu-ray or hard drive. That file is encrypted such that it can be viewed only on devices you've registered with the digital distributor. This would cut down on piracy and at the same time give people a greater sense of ownership.
