Microsoft have said that their Xbox 360 HD-DVD add-on will be the cheapest on the market.The DVD Drive was revealed at the DVD forum event in Los Angeles this week, and although an exact price and date has not yet been announced, Major Nelson has revealed in a podcast on his blog site that," it's going to be the cheapest HD-DVD player you can buy without a doubt, when it comes out. I think it's going to be a great value... Everybody is very enthusiastic with the direction we're going. There's still a few surprises left. And I don't want to spill the beans yet, but I think people are going to think it's a great value."

Microsoft also demonstrated how the Xbox 360 user interface will change. The new interface will see the 'Open Tray' icon on the dashboard be replaced with a button that can toggle between DVD and HD DVD options with the up/down arrow keys. The drive will also allow for software dowloads for new features via XBOX Live.

The add-on is expected to retail at approximately $200.
