Re: Nope, it's rather the opposite.

This is odd logic: Nikon and Canon already make most of the APS-C sensor cameras anyway and are not trending down.  More likely they want to shift users into a price bracket where they have less competition and can thus command higher margins.

They aren't growing and meanwhile NEX and m43 were closing the gap with cameras like the D7000.  They haven't closed the gap yet obviously, but they will in a few years.

Who's not growing?  what is the source for your assertion?  Certainly not the CIPA industry numbers.

Also, why would a FF lens be less expensive to produce than a lens for a smaller sensor?

Many of the "less expensive" FF lenses are less expensive because they are older designs that already amortized initial costs.  New lenses tend to be more expensive unless designed to a specific price.

But old lenses generally aren't sharp enough for the new resolutions so something with tighter tolerances is required anyway.

What old lenses are you referring to? My 35mm f/2, 50mm macro, 85mm f1.8, 1st version 70-200mm out resolve any similar lens on the NEX 7 according to most tests.

Besides, APS-C lens volume probably outstrips FF lens volume, so APS-C lenses can also amortize these costs.

mainly kit lenses.

The salient advantage of FF is more dynamic range, and better low light performance for "reasonable" lens designs.  In terms of cost and weight, APS-C has the advantage especially when you go mirrorless (APS-C DSLRs are somewhat crippled by the fact that they have the same legacy flange distance as FF which makes wide angle lenses extra difficult to design.)
