This is interesting. 17.7 million Xbox 360s sold globally at this phase in the console cycle lends some credence to the 50 million+ forecast we have. If Halo 3 has sold through 8.1 million units, then the current forecast of just over 9 million is a bit low. Mass Effect at 1.6 million seems to imply the current 2.2 million forecast is a bit low as well.
