Microsoft's mysterious updated Xbox 360 disc format will add
an extra 1GB of storage to the console's game discs. Current game discs
use only around 6.8GB of a DVD's theoretical 7.95GB capacity, with the
rest being filled up with gubbins such as anti-piracy measures. Digital
Foundry speculates that Microsoft is either greatly reducing or
outright removing the extra data. Extra space will allow developers to
include more (or higher-quality) textures, sounds, movies, and the like
in Xbox 360 games. If you're in North America and want to join
Microsoft's testing for the new disc format, you can

receive a free copy of Halo: Reach for their troubles.
