It's all a game to generate buzz. Those consoles should be retailing for $1499. Then the profits go to the retailers and the manufacturers, instead of scalpers. Price them correctly and scalpers have no incentive to scalp.
Before you go off on this idea. Think about it. The rich kids still get their console for christmas, their parents just bought it from Walmart instead of some guy on Craigslist. The only people hurt by this would be those who get lucky and find them in stores when they are priced at $499.
Such a first world problem too, this is a completely luxury item... nobody needs any of these.
