Nintendo confirmed the news at a special event in Amsterdam this week, where it showed off the sleek new handheld console to gaming journalists.
The 3DS is the true successor to the hugely popular Nintendo DS, which is the bestselling console in UK history.
It is set to be the first gaming device to display stereoscopic 3D graphics without the need for special glasses, with a slider on the unit used to control the depth of the image.
Among the other new features of the console are its built-in motion sensors, 3D camera, analogue pad and StreetPass communications system, which allows 3DS owners to swap data automatically as they walk past each other.
It will come preloaded with a number of software applications, including a Mii Maker, a pedometer, a sound editing tool and even a built-in game, Face Raiders.
Nintendo of America boss Reggie Fils-Aime said: "You have to see Nintendo 3DS to believe it. And it's like nothing you've ever seen before."
