Nintendo recently overtook Sony in market share as the company became one of the 10 most valuable companies in Japan.  The Nintendo Wii continues to consistently outsell the PlayStation 3 in all markets, even though Sony has eight times more revenue power.  

"Nintendo's strength is its ability to create a new market," said Takeshi Koyama, Mizuho Securities Co. analyst.

Nintendo sold 338,000 Wii consoles on the U.S. market in May, compared to just 81,600 PlayStation 3 consoles sold by Sony.  Microsoft sold 154,900 game consoles in the same time period.  To help further boost U.S. sales in the future, Nintendo announced plans to relocate its U.S. marketing and public relations sector to Silicon Valley and New York.

So far this year, the Wii outsold the PS3 2 to 1 on the U.S. market and 3 to 1 in Japan, according to NPD and Enterbrain.

Sony hopes to boost PlayStation 3 interest by promising at least 380 new PS3 titles this fiscal year -- boosting the game catalog to at least 500 titles.  Along with the higher price tag than the Wii, a lack of appealing games is another reason cited for poor PS3 sales.

"We want to meet market expectations with expansion of our DS and Wii sales," said Ken Toyoda, Nintendo spokesman.

Joining the top 10 valuable lists catapults Nintendo into the ranks of companies such as Toyota, Honda and Canon.
