According to reports, while MS has played a significant role in building up the high definition market, they are not really that concerned about how that will play out in the Xbox 360 market. Aaron Greenberg has told a website that the demise of HD DVD does not at all effect the console\’s position as an entertainment system. He went on to comment that just a small fraction actually bought the HD DVD attachment and the main HD focus has always been the Live Video Marketplace.
