You won't be able to buy used games anymore? Boo-smurfing-hoo. You know what a customer who buys used games is worth to a console or games developer? Nothing. Not a damned penny. They make absolutely nothing on used games. You may as well be pirating the game, because the only company making any money off of it is GameStop, and we could all do with less of that parasite in the industry.

Sony and Microsoft stand to lose next to nothing from crusading against used games. Some may argue sales will drop off due to the people who only pay the $60 price tag because they expect to beat it and sell it back to mitigate that cost, but that effect is likely to be negligible. Also, I doubt it causes people to stop playing games entirely. Instead, we will see a rise in the number of consumers who will wait six months for the price of new copies to drop. This will be a win for developers who will actually see profits from a game outside its launch window.

Even if Nintendo never implements such a restriction, both Sony and Microsoft have been tied to rumors. They're the big boys in the industry. The Wii U is very obviously not the second coming of the Wii, and Sony and Microsoft together will dictate the direction of the industry.

The only bummer about this is being able to share games with friends. Given that the games are tied to an account, features such as game sharing allow this to continue unhindered. It might not be as easy as just handing your friend a disk, but temporarily transferring the license from your account to your friend's isn't exactly a big deal.

Further, it doesn't even mean that used gaming is dead, it just means that the developers now have the tools to get a cut. I sincerely doubt that we're going to see a megalith like GameStop disappear overnight. What's more likely is that if you buy a used copy, your console is going to recognize it as a used copy and demand that you pay a fee (probably pro-rated based on the game's age) to reassign that copy's ID to your console. [Insert game developer of choice here] will be a lot less bummed that you bought their game used if you have to pay a $10 fee to play it.
