Nintendo President Satoru Iwata said Friday that rival Sony was taking a different tack from his company and so he remains upbeat about his 3-D portable game machine going on sale next month.

Iwata was responding to a question from an analyst about the possible threat from Sony Corp.'s successor to the PlayStation Portable, code-named NGP, or "next generation portable," announced Thursday.

"We are more focused on drawing newcomers to gaming and appealing to a wide range of people," Iwata said at a Tokyo hotel. "What we do won't change because of what another company is doing."
