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).

As you can see in the chart below (courtesy of Deutsche Bank), the Wii blew past the Xbox 360 back around July of this year and the momentum clearly has not slowed. The PS3 meanwhile still has a long way to go in order to catch up to either the Xbox 360 or Wii. Sony's console sold just 190K units in October and now has an installed base of 5.7 million units in the U.S.

While the Wii's hardware sales have been practically untouchable, the Nintendo console's software sales can't match the Xbox 360's. Microsoft is often heard touting its attach rate for the system, and for good reason. The Xbox 360 has sold about 94 million units of software compared to 73 million units of software for the Wii (see chart below, courtesy of Deutsche Bank).
