Nintendo Co. Ltd. is on track to meet its target of selling 4 million units of its Wii game console globally by the end of the year, with the potential for exceeding that goal limited only by manufacturing constraints, Nintendo of America President Reggie Fils-Aime said on Wednesday.

"All systems are go for reaching the 4-million target we have in our financials by December 31," he said at the Reuters Media Summit in New York. "We will sell everything we make so now it's simply a manufacturing thing."

Nintendo on Tuesday said it had sold 600,000 Wii consoles in the first eight days after its November 19 release in the Americas — and that Wii-related revenue, including games and accessories, had hit $190 million.

"Exceeding (sales targets) is going to be challenging based on manufacturing capacity," he added. "We will sell everything we make so now it's simply a manufacturing thing."

Nintendo, the underdog console maker in the three-way console war, opted out of the technology arms race between Microsoft Corp. (MSFT) and market leader Sony Corp. (SNE) — which are selling super-powered machines with high-definition graphics — choosing to make its mark with an innovative one-handed controller rather than revved up power and high-definition graphics.

Sony debut its PlayStation 3 in the United States on November 17 and has declined to say how many units it has sold thus far. It has targeted 1 million units in North America and 2 million total worldwide, by year's end.

Fils-Aime added that sales of Nintendo's DS and Game Boy Advance handheld devices were also strong and on pace to meet the company's sales targets.
