Kojima: “Eyes get tired using Nintendo 3DS”

In a live stream where series director Hideo Kojima and other members of Konami answered fan questions, they replied in answer to that very question: “We’re going to see what people think and feel. What Kojima is going to do, is decide the right direction."

"This was more of a 3D depth presentation. The real game won’t be like that. Your eyes get tired.” he mentioned further on.
