The Wii freight train can't be stopped. The console now has almost a 2 million lead on the 360 and it's installed base is well over double that of PS3.
The Xbox 360 did pretty well for itself in October, selling 371K units following price cuts for all three models. The Wii, however, did far better, selling 803K units and leading the industry to $1.3 billion in sales. Thanks to the Wii sales spike, the Nintendo console now has a U.S. installed base of 13.4 million units compared to the Xbox 360's 11.6 million (despite the fact that Microsoft launched a full year earlier).
