Exactly. There is a lot of Sony hate and bashing on here, and why? I buy new games and never resell, so I could care less if it is linked to my account. My Steam games are linked to my account. Also, since everything is eventually moving off of physical media, isn't this just a step towards eliminating said media? Everything is eventually going to be download only and linked to your account, what does it matter that they do it with discs now? Will it make all of your games unplayable if your console dies? I doubt it. I see no good reason to think that it would.
Oh yes, and let's not forget that this is a patent. This does not mean that all games forward will use this. This does not even mean that it will ever make it to the PS4. There are a ton of unused patents out there, so there is no reason to equate a patent to something that is definitely going to happen.
So yeah.. If you don't like Sony, don't buy their product. "I stopped buying anything Sony years ago after such and such incident." Who cares? I know Sony doesn't, and your hate for them is not going to prevent me from buying their product. I am not a sheep, as some would say. I get many hours of enjoyment out of my PS3, and I have no quarrels with Sony. They have a product that I want, and it is a good product.
