Nintendo's game releases for the rest of 2013 include Super Mario 3D World, 'Donkey Kong Country: Tropical Freeze, Wii Party U and Wii Fit U.
"As long as we create high-quality software we will be able to drive our business," Fils-Aime said. Regarding the price cut, he said: "Now is the right time to offer better value. This sets us up for a strong holiday season."
Sony's new console, the PlayStation 4, is due November 15 with a $399 price tag. Microsoft has not announced an exact launch date for its new Xbox One, which will cost $499.
Nintendo also announced a new handheld gaming device that will join its successful DS line. The Nintendo 2DS, coming October 12 for $129.99, will play all DS and 3DS games although it will not display the latter games' three-dimensional graphics.
Like Nintendo's DS models, the 2DS has two screens; unlike them, it does not fold up. Fils-Aime said the 2DS is intended to appeal to "the entry-level consumer looking for lower-priced access to a fantastic library".
