Apparently, the HD DVD drive add-on for the Xbox 360 has been selling like hot cakes. The HD DVD Group announced back in April that it sold over 100,000 standalone players in the U.S. in its first year of being on the market. These numbers did not include HD DVD PC drives or the Xbox 360's peripheral. More recently, however an MS representative stated that the HD DVD add-on has sold over 155,000 units in the U.S., over 50% more sales than the standalone sets. Perhaps the $200 price tag, or less, has really helped push units. Do you have an HD DVD drive for your 360?
