All this refers to is that the manufacturing costs haven't been set for this year-- likely due to Nintendo still selling off the batch produced last year. Last year, was a record low production year and the units still remained profitable. If 2015 actually happens to be a peak year, the costs of production should actually decrease with volume.
Perhaps the report is alluding to the liklihood of a pricecut on the hardware?
I predict NX launches in 2017 - not 2016
