As the video game industry begins to ramp up for the holiday season, Microsoft announced Wednesday that it has cut the price of its line of Xbox 360 gaming consoles. The new pricing, which goes into effect Friday, starts at $199 for the low-end console, the Xbox 360 Arcade model. For consumers, the golden price for a gaming platform is $200 or lower. Consoles retailing at or below that price point account for more than 75 percent of the systems sold, according to Microsoft.
