Future Xbox 360's to Feature HD-DVD?

In this article from GamesIndustry.biz, Bill Gates, speaking in Tokyo at a joint Microsoft/Toshiba event, intimates that future versions of the Xbox 360 may feature HD-DVD, Toshiba's next-gen DVD standard. Sony's rival Blu-Ray technology will be featured in the PS3. For now, the Xbox 360 will ship with the basic DVD drive. The addition of the HD-DVD for future iterations of the 360 will most likely be more for movie watching than game playing, although perhaps game publishers will publish "HD" versions of their games in addition to the normal "DVD" versions. This is all a push to make the Xbox 360 the center of your home entertainment system and to usher you into the "HD Era".
