I seen on the news today that ebay has posted rules on selling the ps3. When the xbox was out last christmas some people were selling the acutally box it came in and people were paying over 800 for a xbox box. Here are the rules for ebay people tryung to sell the ps3.
Only established eBay Inc. vendors -- those who have racked up comments from at least 50 previous customers and have positive ratings of at least 98 out of 100 points -- can list PS3s before tomorrow.

Each vendor can list only one PS3 per eBay account.

The listing must include a photo of the pre-order receipt, and the seller must guarantee shipment within 30 days from the date of purchase.
