Even if the low end of this prediction is true (25 million) that's insane. That is like peak wii levels. If they hit the high end (30 million) then now we are in peak DS levels which is even MORE insane.
So Nintendo spill it. What in the world are you releasing in 2018 that will cause sales to skyrocket to such a degree? I can't think of any title by itself that can make sales go this high. It has to be a combination of big titles. Is it Pokemon + Animal Crossing + 2D Mario + New IP? Now I cannot wait to see what is at the January Direct (I predict a January Direct).
