You should probably take this with a grain of salt as big as the VW Bug but according to this
thread over on Evil Avatar, EB Games is going to be terminating all PS3 pre-orders it finds on eBay. How are they going to know you ask? Well, the new eBay policy requires people to post a copy of their pre-order receipt and since those receipts have order numbers on them they will know which orders do not belong to the original owners. This means two things. The first is that if you bought a pre-order on eBay you might have just spent a lot of money for nothing and that there might now be more units available at launch from those whose pre-orders were canceled. I guess we'll find out in 18 days or so.
