Nintendo 3DS is a new, more powerful, platform than the Nintendo DS. Therefore, development costs are bound to up. And when development costs go up, the price of software goes up too.
Despite this, Iwata believes that 3DS software won’t change much from its previous platform’s pricing. “We don’t believe that the world is in a state where high priced software will sell well, so we don’t believe it will be in a price range too far off from current DS software.”
Most newly released titles on DS range from about $29.99 to $39.99 in North America. So even if it is $5 to $10 more, it still falls at a pretty low price point. Although, 3rd parties have some wiggle room of their own, as Square-Enix charges $39.99 for pretty much every DS title they launch, with the exception of Final Fantasy: The 4 Heroes of Light.
