40nm will only be cheaper per transister up to a point when compared to a newer lithography.

Actually that belongs to 28nm ...

20/14nm is when cost per transistor will rise cause of the fact that double patterning is needed to achieve smaller feature sizes ...

No, it belongs to every fabrication process ever used and will ever be used.

There was a reason why Intel was slow to move Atom to a cutting edge lithography, why they used to release it's motherboard chipsets a lithography or two behind it's processors, it was costs and profit margins, it was simply cheaper to use the older lithography.
