As was the case with the release of Halo: Reach, Microsoft are releasing a Halo 4 version of the Xbox 360, when the game is released on November 6, 2012.
Like other limited edition consoles, it will come with two pads, game-specific sound effects and an exclusive Halo 4 design.
The console was briefly posted on Microsoft's online store with a price of $399.99, but has since been removed. Here's the image first spotted and taken from the site by IGN.
