Lets be honest we all saw this coming, every time a BIG game comes out and is even "exclusiving" itself to the 360 they make a BA custom console. Personally I have to get one as I have gotten one since MW2's custom 360, and this is one beast looking design.

Whats in the box
Gears of War 3 custom Xbox 360 (has a 320GB HDD!)
2 wireless GoW3 custom controllers (the new ones with the fancy d-pad!)
copy of Gears of War 3
a code for some exclusive DLC
