The next version of Xbox Live goes public beta. Microsoft is inviting users now.
Looks like somebody had to work on 4th of July. Microsoft's Major Nelson just announced the the launch of the public beta of the next Xbox Live Update. Sign-up now as space is limited. New this time is that you can sign-up directly through the Xbox 360.
To get access to the beta look for the Xbox Beta Program tile on the home hub in the Xbox Dashboard. You have to agree to a NDA. The beta FAQ will be posted later today here. Microsoft wants you to give them feedback on the beta so they can put on the finishing touches for the release.
