From Gizmodo:
Peter Moore had a recent interview with the Japanese website ITmedia where he admitted that the Xbox 360 could possibly see a Blu-ray external add-on. Even though it was announced at the Microsoft keynote at CES that the HD-DVD add-on would be coming soon for the Xbox 360, Moore said this isn’t certain. Because the 360 will be using an external add-on it allows Microsoft to adapt whatever the hell next-gen disc format that it wants. Moore did confirm the fact that Xbox 360s will never be shipping with any kind of next-gen drive already integrated into the console. Biggest twist of the year in the next-gen disc war?
