Infinity Ward has announced the three editions of Modern Warfare 2 for Xbox 360 coming out November 10th this year: Standard, Hardened Edition and Prestige Edition.

The last one includes fully functional night vision goggles. Yes, that's right. Not a game accessory, but fully functional night vision goggles you might use to roam the neighborhood at night. 
I do not dare to imagine what this will cost, but I will try to get my hands on one of them when they come out in November.

Check out Infinity Wards own video showing of the package.
