If they put it up for auction before nov. 17, ask the seller to send you a picture of his preorder slip. Then call the gamestop and tell them its up on ebay. I heard that gamestop doesn't want their systems sold on ebay and that they'll cancel any preorders that are being auctioned.
I'm number 6th on the list so I'll be chillin at the crip playing resistance on the 17th
