I think they were expecting more, maybe twice more, but as an old industrial quoter engineer who already had experience with quoting cardboards, these sales has probably been a huge easy money for Nintendo. If one of these cardboard has an industrial price of 1€ - 1€50, multiplied by 6, + an average quality software which was not very expensive to create I believe, I think they make nasty margin in selling these 69 and 79€.
