According to the Nikkei piece (viewable here), Nintendo now looks at Asia as being wide-open and up for grabs. The company apparently plans to redouble its efforts in South Korea, Taiwan, and China.
The Nikkei reported that the 3DS would launch in South Korea on April 28. This summer, the Nikkei added, it would hit Hong Kong and Taiwan as well as China. In China, however, the portable would be rebranded the iQue3DS as Nintendo handhelds are called "iQue" in China.
Nintendo released a statement: "Concerning the Nikkei report 'Nintendo Targeting the Asian Market', the article isn't anything our company is possibly announcing, nor is it anything this company is confirming. What Nikkei wrote is based on speculation."
One thing that isn't speculation: In Jan. 2011, Nintendo trademarked "iQue3DS" in China.
