One thing that Nintendo have caught some flack over during the last couple of years is their lack of support for third-party developers. This has been mostly obvious on the Wii, but in the future it looks as if that's about the change.
During a shareholder call, Satoru Iwata was asked "how will the software releases for the Nintendo 3DS and the Wii U be from now? Also, are software publishers collaborating with Nintendo?" to which he answered, in part:
"[W]e think that it is important to encourage the software publishers to think "This is a platform on which we can perform our business" in the very first stage of the platform. We think it very important to make several hits from the third-party software publishers within the first year from the release of the platform, while offering Nintendo software seamlessly."
"In order to achieve this goal," Iwata continued, "we have shared information about the new hardware with the software publishers earlier than we did previously and built a cooperative structure, and we are developing several titles in collaboration with these publishers. I cannot talk in detail about the names of the titles, or with which publishers we are currently collaborating, because we have not announced this information yet, but what we are aiming for with the Nintendo 3DS and the Wii U is, platforms which have much more software and a wider variety of software than the former Nintendo DS or Wii. Therefore, we are thinking of creating an environment where software from other companies will become hits. Please understand that Nintendo is prepared to invest in order to make this a reality."
