If true, such a move would be a massive boost for publishers and developers which do not profit from the lucrative and damaging retail trade in used games. In fact, many publishers are furious that they have to spend support money on consumers who have not actually contributed a dime to the company's coffers.
Like I give a crap if they made a shitty deal with Sony. Why should the consumer be punished? Let them be "furious" with whoever they have negotiating for them for screwing up.
In turn, it would be a catastrophe for retailers, which make a significant proportion of margin from used games. Consumers would likely be less than overjoyed.
If this is so, I'd like to believe the retailers will boycott the PS3 over this foolishness, but I'm not willing to bet on it.
Sony, which is refusing to comment on the story, does have a patent on technology which would tie a piece of software to an individual piece of hardware. But technology and desire are not the only parts of the puzzle. Whether the company would be prepared to take on retail, consumer goodwill and, most likely, the U.S courts, is another matter.
First, I give it two weeks before someone cracks that piece of technology once the PS3 comes out. Second, this plan's going to go over about as well as the music industry trying something analogous with a CD.
Edit: About the 5 million units of the PS3 that Sony thinks they are guaranteed to sell, even assuming they move that many, it's going to take much more than that, both in hardware and games, to make them a profit. If they piss off everyone but the 5 million theoretical lemmings they imagine will pay for this, they're seriously up a shit creek. Losing money and building goodwill is one thing; losing it by pissing off gamers is another.
