Digital Foundry :
"I was there when Nintendo first pitched the Wii U to developers, I worked on the hardware extensively and helped to produce one of the better third-party titles. Now, as the fate of the hardware looks uncertain after a second Christmas of disappointing sales, I wanted to tell the story of what it was actually like to work with the console, and with Nintendo, and perhaps give some context to the mixed fortunes of the machine and its third-party titles.
But first, let's go back to the beginning. The genesis of a new games console generally follows a standard pattern. Initially there is a prolonged period of research and development internally within a manufacturer where the goals and hardware designs are sketched out. These then go through a process of refinement with the hardware parts manufacturers, based on their technology and, obviously, cost."
