Coming from a WSJ interview with Nintendo's Shinya Takahashi...

“We have walked many roads and really struggled before coming up with the concept."

Coming from producer Yoshiaki Koizumi...

“We looked back at what Nintendo has done, and when you think about it, it’s really been an amusement provider. When the concept was set, most of the Switch’s basics came together quickly. Things like, you have to be able to take the controller outside, and you’ll need two of them.”
