Microsoft's new Xbox One will come complete with a Blu-ray drive. Games for the new console will be stored on Blu-ray discs, matching the PlayStation 4 as well as the Wii U's high-capacity proprietary media. It's not currently known what speed the Blu-ray drive runs at.
The move marks an about face from Microsoft, which opted to support DVD media on the Xbox 360 while Sony's PlayStation 3 made use of Blu-ray technology. Microsoft released an HD-DVD drive accessory for the Xbox 360 in 2006, but it was only ever used to play movies stored on the ill-fated format. The player was discontinued in early 2008.
