The folks over at Ars Technica are reporting
that Microsoft will be releasing a $400 Halo:Reach
themed Xbox 360 later this year in conjunction with the release of the game. The unit will be a silver version of the new Xbox 360 slim (the 250 GB version) and will come with two wireless Halo themed controllers.
The mole that Ars gets their rumors from is usually pretty accurate and honestly given Microsoft's propensity for limited editions of their hardware it would have been more of a surprise if there wasn't a Halo:Reach
version (I'm guessing there's going to be a Gears of War 3 version as well). We'll get images up as soon as it's announced.
