In a new interview, Nintendo's Shigeru Miyamoto discusses the Wii U's shortcomings and promises an improved UI is on the way.

Speaking with Time, Miyamoto addressed user complaints regarding the Wii U's user interface. "Even during the testing phase, it's difficult to ascertain what facets of those interactions between the applications are resulting in inconveniences for the consumer until you have an opportunity for many people and lots of consumers to try these features out." Miyamoto said. "What we want to do is make sure that when we release [the update], that we address as many of the different opinions about how people would like to see the system improve as we can at once. We hope to cover a wide range of requests while simultaneously ensuring it's a very stable update to the system."

Miyamoto went on say users can expect the update by summer, stating, "...the system is going to be very much improved over how it's performing currently."

Earlier this year, Nintendo President Satoru Iwata took personal responsibility for the Wii U's sluggish sales, declaring a 100 billion yen operating profit goal for the next fiscal year.
