"Each game console has its own unique qualities, and developers must go through a trial and error phase to acquire the knack of taking full advantage of them," Iwata told investors. "This time does not come until a final version of the hardware and development tools for the version have been made available and then a base for software development has been established. For Wii U, such a time finally came in the latter half of last year. In this sense, we could not avoid the trial and error stage to create games which take full advantage of the hardware."
Iwata noted that this situation is encountered not only by third parties, but Nintendo's internal teams as well. The executive noted that his own teams have almost emerged from that trial-and-error phase, and are just now becoming familiar with their company's own hardware. LINK
