These are my feelings exactly on this, and I couldn't have said it better myself.
That said, I'd like to add a little:
Video game publishers/developers/etc are running BUSINESSES, and no business has a right to profit, only the right to try to make a profit based on the choices THEY make as businesses.
The possibility of failure comes with the territory, and is something anybody running a business must accept as a result of THEIR choices as a business, not the choices of others.
If customers aren't buying a business's product/service (and aren't stealing it either, as that's another discussion altogether), it is up to the business to adapt their strategy to bring in new or more customers. If they can't adapt, then another company eventually will, and the original company may lose their business.
In this case potential customers are choosing used games over new ones. It is up to publishers to adapt to a changing market (which of course they are), and to reduce the Hollywood-like budgets and waste going into modern games.
This all has nothing to do with used game sales, and all about what people are willing to spend on a new (to them) game. The markets for used goods of all kinds will always exist (ebay and craiglist are quite popular), and thet aren't going anywhere.
Seriously: It took ~ $5 million to produce GTA IV. I felt at least a little ripped off after paying $50 for a game that barely runs on my PC with the settings turned down, despite it exceeding the RECOMMENDED specs for the game. Not to mention the lackluster storyline. This sort of thing loses the trust of customers. Why would I buy a new game if it will almost certainly be buggy on release? I could just as easily wait until well after release and then get a game with the bugs ironed out for a lower price to boot. As far as the game play, story and other in-game content is concerned, if I had bought a used game, I could have relied on existing peer review, rather than bought-and-paid-for reviews that are put out for upcoming and new titles.
There are many areas that the used games market is favorable over the new games market. And it is up to the publishers to adapt to this, and give their (potential) customers reasons to trust them with their money by putting out quality products that people WANT to pay for to get new, not to attack a legitimate competing market.
