According to a forum poster on Evil Avatar who implies he's a manager of an Electronics Boutique in Canada, eBay, Sony, and EB will be working together to track down and cancel any pre-orders of the Playstation 3 that appear on the auction site.
Referring to an eBay policy restricting console pre-order auctions that requires a picture of the receipt, the Evil Avatar poster claims that EB will remove the Playstation 3 pre-order from their system for any receipt from EB that shows up in an eBay auction.
I don't yet know if it's true, but the general lack of bluster from the poster gives it some air of plausibility. And if EB Canada is doing it, perhaps Gamestop and EB in the US will do the same - giving me a shot at picking up a PS3 pre-order again.

Update: According to Next Generation, the rumor is baseless. A pity!
