Nintendo president Satoru Iwata has revealed that the company’s successor to the Wii could have ended up as a portable rather than a traditional games console. Speaking to online gaming publication Gamasutra Iwata stated that Nintendo were previously thinking about making the Wii U a standalone system, rather than making it work with a base system. Would you have preferred Nintendo to take the portable route with the Wii U, or are you happy it’s a brand new home console?

“During the roundtable discussions there were such arguments about should we make it capable of being a standalone system or should we make it work only with the [base console] system,”

“We came to the conclusion that this controller is only going to show the images generated and processed by this hardware unit — and sent from the hardware unit wirelessly. That means sharper graphics. A battery couldn’t do that.”
