A European Microsoft representative has indicated (http://www.engadget.com/2006/04/20/microsoft-to-announce-hd-dvd-at-e3/) that the XBox 360 HD-DVD drive add on will likely be announced at E3 this year. Depending on the price of the drive, this could make those of you who have bought an XBox 360 that much happier with your investment :)
