Nintendo said Friday it will launch a video-game console that will be as portable as the cell phone.

The Japanese game maker said its Game Boy Micro will be available in Japan on Sept. 13. The product will be available in U.S. stores one week later.

Nintendo expects sales of its latest toy to reach 4 million worldwide by March. In addition, the company said it expects to sell about 10.2 million of its desktop Game Boy Advance consoles during the same period.
