Nintendo of America president Reggie Fils-Aime has confirmed that the 3DS' next firmware update will introduce a framework that will allow developers to sell extra downloadable content for their games. He also confirmed that Nintendo themselves will offer DLC for its games as well. However the introduction of DLC for Nintendo games will not dilute the content of a players initial purchase, and that they will still enjoy a complete gaming experience even if they do not purchase any DLC.
In an interview he stated:
"In terms of what the next system update will allow, it will allow developers to sell add-on content, and whether that's for a physical game or a digitally released game," he said. "In terms of how it will work, it's up to the developer whether they want to make it to buy new levels, new items--all of that is up to their imagination. Essentially, what we're doing is creating the framework for those transactions to happen."
