Microsoft today ended its E3 keynote with a bang, unveiling a leaner, meaner Xbox 360. The redesigned model occupies less space, runs "whisper-quiet," and gets some heavily upgraded accessories. We haven't spotted a specific name for the new iteration, but it's supposedly already shipping out to retailers and it should be on store shelves near you by next week.

Pricing will be the same as the old 120GB Elite model ($299), but the revamped unit has a built-in 250GB hard drive as well as 802.11n connectivity. Microsoft reportedly plans to keep selling the existing Elite Xbox 360 at a reduced fee of $199, while the basic Arcade system will sell for $149. It's unclear whether this pricing is permanent or if the company is just trying to gut remaining stock.

Additionally, Redmond has slapped a price tag and ship date on its motion controller. Kinect (formerly Project Natal) will hit stores on November 4 with a stand-alone cost of $150, which is in tune with previous rumors. It will be accompanied by at least 15 games when it launches, and you can take a look at that list after the break.

Some games expected to launch with Microsoft's Kinect motion controller:
  • Game Party in Motion
  • Motion Sports
  • Kinect Adventures!
  • The Biggest Loser: Ultimate Workout
  • Kinect Joy Ride
