From what I can gather, this is just a rumor. The retailers would get killed on this, because the millions of PS2's bought for Christmas would be eligble for a price match from BB, Circuit City, and the others, since the price changed within 30 days of their purchase. These retailers would lose a TON of money, and in turn would probably stop selling the PS2, to screw Sony. And the PS2 would essentially sell less, despite the lower price 
They'd probably do it as a mail in rebate that would be extended to units purchased after Dec.1/2001. This happens all the time on other goods.
