Microsoft updating Xbox 360 disc format

Microsoft is gearing up for the next Xbox 360 system update, but it needs gamers' help testing a few things out. The company today announced a new System Update Preview Program for US-based Xbox 360 owners to help test a new disc format for the system.

By signing up at the Microsoft Connect website and filling out a survey, US gamers can volunteer to take part in the preview program. Multiple thousands of gamers will be chosen to participate, with Xbox Live Gold members receiving priority over their nonpaying Xbox Live Silver counterparts.

Participants will receive a copy of Halo: Reach (and possibly other rewards as well) for their trouble, but the program is not without risk. During the registration process, Microsoft warns that due to the nature of prerelease software updates, there's a chance participants could wind up with nonfunctioning systems. The agreement makes no mention of Microsoft repairing systems broken as a result of the update.

When asked what security or storage benefits the new disc format might bring, a Microsoft representative told GameSpot there were no additional details to share at this time.
