Steve Ballmer of Microsoft has confirmed that they are developing software that will support Sony’s Blu-ray high definition movie format to the Windows operating system (OS). He avoided questions about Xbox 360’s Blu-ray support. Microsoft Xbox 360 is the major competitor of Sony Playstation 3.

“We’ve already been working on, for example, in Windows, device driver support for Blu-ray drives and the like, and I think the world moves on,” said Ballmer at the Mix08 conference.

“Toshiba has moved on. We’ve moved on, and we’ll support Blu-ray in ways that make sense.”
