Special editions

On a few occasions, Microsoft has produced special editions of the console, usually to coincide with the release of a major product. These special editions are typically custom-colored Xbox 360 models, and are produced in limited numbers.
At the E3 2007 press conference, Microsoft announced the Halo 3 Special Edition console, released September 16, 2007. It sports a Halo 3 theme on the console, wired headset, wireless controller, and play and charge kit. Other than the unique "Spartan green and gold" color scheme, exclusive dashboard theme and downloads, and a HDMI port,its features were identical to those of the Premium system at that time.It is priced at US$399.99 and £279.99 (the original price of the Xbox 360 Premium).
To promote The Simpsons Movie, Microsoft created a specially designed, yellow Xbox 360 console.The configuration was based on the Xbox 360 Premium package of the time, the only difference being the color scheme of the Xbox 360 console and wireless controller. The consoles were to be given out to winners of drawings taking place between July 18, 2007 and July 27, 2007, in which a name was randomly drawn each day in the "10 Days and 10 Chances to Win" sweepstakes. Ten consoles were produced in total.
