Nintendo head honcho Satoru Iwata hinted at the possibility of paid DLC for two of its 3DS titles, Super Mario 3D Land and Mario Kart 7, at a recent investor meeting. Speaking in terms of hardware and software lifespans, Iwata suggested (hypothetically) Nintendo could benefit from the addition of paid DLC to both Super Mario 3D Land and Mario Kart 7:

"What if we could provide add-on content through the network?" Iwata asked, positing a solution to the problem of players growing tired of the games they've purchased. "As I referred to before, for example, this is the idea of supplying new stages to Super Mario users who want to play the game more but have completed the game and lost interest in the existing stages.

"This will not only give us new profits but will lengthen the life of a product, in that it will never be out of fashion and can keep attracting public attention as long as many people play it." DLC functionality was added to the 3DS with the last firmware update, and will first be used in a retail title in Japan with Theatrhythm: Final Fantasy.
