Citing retail sources and market analysts, the New York Post had an article on the 18th that referred to Microsoft's "flagging Xbox video game console" and suggested that a price cut to $150 may come as soon as April. Thanks TheElderGamer at Xboxsolution.
UPDATE: Several sites are claiming that MS is denying this rumor; however, I've yet to see any citation or anything directly from Microsoft. Could be just the Post dredging up... well, what the New York Post usually dredges up.
