In the United States, there are approximately twice as many Xbox 360s in play as Sony’s PlayStation 3 — 14 million for the Xbox compared to almost 7 million for the PS3. This figure, however, doesn’t tell the whole story: If you look worldwide, both consoles gain about 10 million units sold, which results in a closer gap of 24 million to nearly 18 million. Plus, Microsoft rushed its Xbox 360 out the door a year faster than Sony’s November 2006 launch of the PS3 … and Microsoft may still be paying for its haste via an extended warranty program.
