No. Then Wal-Mart, Target, Best Buy, Future Shop, etc would get a larger sure of the passed up revenue. It would be suicide for GameStop.
Why? They could spend time educating customers by saying they refuse to stock such an anti-consumer game system. They barely make any profits on the system and new game sales anyway, so what's their loss by refusing to stock it? Walmart makes their money on all the other non-gaming crap you buy while going in to buy the system.
