@bobc,
Having recently gone through microcontroller selection at 1k quantities, I found Atmel was still coming out on top as far as low cost goes. ATSAM, that is.
When I added requirements for: USB, PWM, at least 12ADC channels, and 64kB of Flash, the cheapest ones to pop up were ATSAM3S1C at $2.44ea @ 1k (us.digikey pricing. Actual should be lower). And those are 64MHz Cortex M3.
