Nintendo's new console-handheld hybrid Switch was unveiled earlier this month, and while gamers are intrigued by the possibilities, investors have not been. Shares in the company are down 10% since the reveal, and Nintendo President Tatsumi Kimishima is a bit perplexed as to why. 

"To tell you the truth, I was surprised," Kimishima told Bloomberg when asked about the shar price drop. "I had wondered about the reaction. But I don't understand why. And there's no real point in me talking about the stock price."

He said Nintendo has had revenue drops in the last eight years and only after Switch is launched next March will the company know if it is on the right track with fans. "What we aim for is to increase the number of people who play games," Kimishima said. "We want to deliver all kinds of new surprises to our customers, and it is through their support that our revenue increases. That's the end result. But if that result doesn't show, that means we weren't able to deliver. Next year is when we see the result."

As for what else the company is working on, Super Mario Run for mobile is a major initiative, and Kimishima has tasked creative head Shigeru Miyamoto with making sure the game delivers on expectations. "We all saw what happened when we delivered Pokemon Go," he said, referring to the massive numbers of players adopting the game at launch in various countries. "And honestly I was quite surprised by it myself. There's no doubt that more people are using smartphones to play games. And as this time we're using Mario, that's a very important intellectual property for us. And that's what Miyamoto's team is working on now: making sure it spreads out just as quickly as Pokemon Go."

A tall task, indeed, but one Miyamoto's credentials are aptly suited for, especially given Mario's popularity. "More than 20 million people have already registered to receive notifications when the game is available," Kimishima said. "In terms of the game itself, you can download it and play a certain part of it, and then pay a fixed price and then play it over and over as many times as you want without having to pay anything extra. And that should give peace of mind that kids can play it. And we're hoping that will help it become more popular."
