I could be wrong, but I suspect that between the new models, the price reduction, and the sales history of the PS2 many retailers in North America probably expected the PS3 to sell 2 Million units in November and December; this would mean that they would still have half of their holiday inventory. I suspect that if this is true you will probably see some pretty smoking deals on the PS3 soon.
