Microsoft will expand the closed beta of the 2012 Xbox Live update with a new round of testers in the coming weeks. The platform holder has re-opened the application page for entry into the beta, but numbers will still be limited so don't hang around. The beta first opened up in July when MS took in the first round of volunteers to test out a pre-release version of the new dashboard features set for arrival later this year.

- Enhanced category search and discovery features
- Voice search (in specified markets)
