As Nintendo prepares to transition to the 3DS, the company is looking for ways to continue serving its large install base on the Nintendo DS. One way may be to localize games that have yet to arrive in other territories (via Siliconera).
Speaking with investors, president Satoru Iwata said that localizing games from the DS’s large library may be a way to take advantage of the current DS library. He cited Animal Crossing for the GameCube as an example, which wasn’t slated to be localized until Nintendo’s localization branch evaluated it and determined it would be viable in the west.
There are plenty of DS games that have yet to be localized, including Soma Bringer, 7th Dragon and Blood of Bahamut. Nintendo has also yet to announce whether the latest Fire Emblem remake will be localized.
