If Wall Marts USD100 2DS was the floor in 2013, the floor in 2016 will be probably considerably lower since it will be cheaper to manufacture.
As long as they make a profit they shouldn't worry about making the console cheaper. PS3 is much much cheaper nowadays than in its first year.
I think the console has 2 more years of selling over 10 millions with a normal price, and 2 more year of selling whatever it sells with a large price cut.
