Microsoft says its next-generation Xbox 360 console will go on sale in the United States on November 22, in time for the Christmas shopping season.
Its European and Japanese debuts will take place a few weeks later.
The software giant hopes to take the lead in the $35.72 billion video game market from Sony.
The PlayStation 3 will hit the US market early next year.
The current Xbox is level pegging in the popularity stakes with Sony’s PlayStation in the US but is lagging behind both the PlayStation 2 and GameCube in Japan, with fewer than 500,000 consoles sold compared to 18 million PlayStation 2 sales and 3.8 million for the GameCube.
Gamers got to experience the Xbox 360 at the Tokyo show and will have another crack at the new console at the Xbox 360 Lounge, opening in Tokyo in November.
