Tretton also stated that demand for the PS3 means that consumers will be willing to pay over the odds at launch.
“I think the consumers that get their hands on a PlayStation 3 clearly see the value and not only want to buy one for $599, in some instances they’re willing to pay ridiculous prices on eBay,” he said.
Here's the PS3 eBay page. First, note that there's a ton of inventory. Next, observe that there are indeed a lot of sellers asking ridiculous prices, but not a lot of buyers at those levels. The action seems to be on the many, many units which are selling below MSRP.
