It will be a boat/airplane console, so conquering an up until now unexplored market, and giving Ninty a monopoly on it tht will last undisputed for at least four year, worst case if competitors will react as quickly as possible to put their competing device on the market.
It will use three or four additional sensors, made each with 3 gyroscopes and 3 accelerometers, to be bolted or riveted on the deck in a triangle or square shape to provide info on the vehicle motion to be subtracted from the motion control interfaces info vectors.
Later Ninty will be able to grab another monopoly adding sensors to detect gravity or its absence and making the spaceship console.
