In a recent investor Q&A, president Satoru Iwata said Nintendo will most likely have some new software ready this year that has not yet been announced. He also said the company is planning to launch this year's games starting around mid summer.
Iwata says the Wii U's value is hard to understand until you've tried it, but that with the right games combined with more creative messaging, Nintendo can get that value across. He says once you've used the Wii U for a while you really understand its appeal.
When asked about the power of the Wii U's architecture, Iwata said that developers must always "go through a trial and error phase to acquire the knack of taking full advantage of [a console's unique qualities]," and that this time comes once the hardware and development tools are finalized, which happened for the Wii U in the second half of 2012. Having gone through some that trail and error, Iwata believes "that our in-house development teams have almost reached the next stage."
Iwata was also asked about the Wii U's so far unused NFC scanning capabilities. He says Nintendo is working on NFC, and " by the end of this year ... will probably be able to show you some output, tell you about some more concrete examples of the possibilities or even let you try out some tangible examples." So it doesn't sound like we're likely to see any Nintendo products released that use NFC for a while still.
