In an interview with Japanese site ITmedia , Xbox VP of marketing Peter Moore said that if HD-DVD loses the next-generation DVD war, Microsoft could still develop a Blu-ray Disc drive for the Xbox 360.

"Since we're using external drives [for next-gen media], we can change as the market changes," said Moore, according to remarks translated by Gamasutra from the Japanese original. "Sony can't do that. If Blu-Ray wins, that's a big chance for Sony. But if Blu-Ray fails, it will be a considerable blow for them."

Moore did not address the possibility that Sony, like Microsoft, would also consider add-on drives for the PlayStation 3 in the event of a shift in popularity to HD-DVD, which currently has fewer Hollywood supporters than Blu-Ray.
