Microsoft unveiled its smaller, sleeker Xbox 360 design, packing a 250GB hard drive and built-in wireless-n. Microsoft's Don Mattrick said it will be in stores by the end of the week, and will still cost $299.

The Official Specs:
* Touch Sensitive Buttons - turn the Xbox 360 on or off and eject a disc with the swipe of a finger
* Whisper Quiet - Whether you're playing a DVD disc or from the hard drive or navigating the dashboard, with the all-new and much quieter Xbox 360, the only noise you'll hear is your own laughing, cheering and playing
* Wi-Fi - Built-in 802.11n Wi-Fi for fast, easy connection to your friends and entertainment on Xbox LIVE.
* Hard Drive - 250GB internal, swappable hard drive for even more storage. To access, remove the bottom panel by pushing the small tab toward the front of the console.
* Kinect-ready - Custom Kinect port on the back of the console that directly hooks up to the Kinect sensor for controller-free fun.
* USB Slots - Five USB ports, three in the back and two in the front.
* Power Supply - Smaller and more efficient. Xbox 360 250GB and Xbox 360 Original power supplies are not interchangeable.
* Wireless Controller - The award-winning Xbox 360 Wireless Controller matches the console in all black with color-matched thumbsticks and directional pad with a touch of gloss and chrome to complete the look.
* Backward Compatible - Your favorite accessories and games will work with Xbox 360 250GB. Xbox 360 external hard drives and Memory Units are not compatible.
