Nintendo is currently preparing a paid item transaction system for both 3DS and Wii U, Iwata revealed. For 3DS, this will be available to developers by the end of the year.

Nintendo may be selective in its use of this system for itself, though. Iwata and Shigeru Miyamoto are interested in the possibility of extending the life of games through added stages and other features that players want. However, Iwata believes that pursuing certain types of low quality paid download content opportunities -- things like unlocking keys or stat increases -- would, while likely increasing short term profits, not allow them to build along term relationship with customers. Therefor, Nintendo feels that it should not have this type of low quality content for itself.
