Nintendo has admitted that it put too much emphasis on the controller for the newly revealed Wii U console, noting that it "should have made more effort" to explain the console better.The company has seen its share price fall two days in a row to the lowest in five years, as analysts said that "market expectations [for the console] had been far too high".Talking to the London Evening Standard, Nintendo president Satoru Iwata admitted that the company should have shown off the console first, rather than jumping straight to the controller, although he made the point that "Wii U is about the controller"."Because we put so much emphasis on the controller, there appeared to be some misunderstandings," he said. "We should have made more effort to explain how it works.""We haven't made any kind of blunder, but I should have shown a single picture of the new console, then started talking about the controller," he continued. "The console is not drastically different, and Wii U is about the controller. The console itself will be almost invisible."Iwata said that the press was also to blame, noting that it's not possible to see how important the Wii U console is unless you've actually given it a try."There have been two groups of people writing about our announcement - those who have been able to experience the Wii U, and those who have not, and are simply writing about it from wire stories and pictures," he mused."They cannot see how this can be a game changer. It reminds me of 2006, when we introduced the Wii for the first time. Here in LA, people enjoyed it, but in Japan, the atmosphere was very different. It seems to be the same this year.""What Wii U will offer is very different, but I believe we have the strong potential to change the entire format of videogames and of entertainment," he concluded.
