Nintendo Co. has sold 4.5 million units of its latest hand-held device, the 3DS, in the U.S., setting what the company said was a strong pace and potential momentum for its next big product, the Wii U console.
The 3DS’s sales — $1.2 billion including software — mark an important milestone for the company and its dual-screen portable 3D-game system, which had a bumpy start in the first half of its initial year of sales.
