A Wal-Mart spreadsheet allegedly listing products that the company is having difficulty stocking states that the 40GB PS3 "will be replaced with [a] new model in early August." We received this sheet from an employee that's sent us solid information in the past though s/he can't confirm the origin of the note that the model will be replaced. Of course, in the eternal battle over semantics, "replaced" could simply mean some minor tweaks to the model and the addition of the DualShock 3.
