Microsoft will be releasing a new update to the Xbox 360 soon, adding support for Kinect, ESPN and introducing a revamped dashboard. But there are also a few "under the hood" features Microsoft will be including in that update.

While we've discussed the Xbox Live Fall 2010 update's most visible new features at length, there's more to the update than just Netflix search and Zune music. There are also revamped Avatars!

The following new additions, direct from Microsoft, may not be the sexiest of improvements, but "improved voice quality" sure sounds nice.

  • Improved voice quality – the audio codec is being updated to improve Xbox LIVE Party chat audio quality. So grab your friends and jump into a multiplayer game, catch a big sports event, watch a movie or do all three.
  • Improved experience for changing your Gamertag – choosing a new Gamertag? If the Gamertag you're looking for is already taken, your Avatar will spin a wheel and we will provide five other Gamertag suggestions at a time for you to choose from.
  • Streamlined in-dashboard virtual keyboard – we've taken the existing QWERTY keyboard in-dash and made it easier to use for scenarios that involve repeated text entry, for example when signing up for LIVE within the dashboard.
  • Improved Xbox LIVE Marketplace UI and browse experience – the Games Marketplace has been re-organized to provide streamlined access to the games and content you want, reducing the number of steps it takes to get to a download.
  • Avatar changes – we've made your Avatars slightly more proportional so you can better play Kinect games
  • Easier to get on a wireless network – trying to connect to a wireless network? With the next update, you'll see a list of all the wireless networks within range when you go into network settings. From there, you'll be able to select a new network or further configure the network you're connected to.
  • Ability to sign-out other controllers in the sign-in UI – we're adding the ability to sign-out profiles on other controllers in the sign-in UI within the Guide. This is especially useful when playing games like Rock Band.
  • New browse experience for 100% completed games – you spent a lot of time and effort earning those Achievements, so instead of only being able to view your first dozen completed games, we're giving you a new and better way to browse all of them.
