The Xbox 360, it could do better. At least according to analyst Lazard Capital Markets, and they know this kinda stuff. They are pros! The firm's Colin Sebastian states:

Xbox 360 sales appear to be tracking below current market expectations. Based on year-to-date sell-through trends in North America, we believe sales of Microsoft's Xbox 360 console are tracking closer to 4.5 million units for the year versus current market expectations in the 5-million unit range.

Fear not! This Christmas could provide a boast to slightly sagging 360 sales, thanks to PS3 shortages. Microsoft's just gonna ski in the Wii's and PLAYSTATION 3's launches. But, for how long? Brian Ashcraft
