Hi all,
When I first tried to introduce PICs to the company 5 years ago, 
I asked the local Microchip person to recommend a popular low cost
MCU for me since we need to support our device up to 10 years or 
even longer and want the potential to get lower cost in the long run.
The particular device used was PIC16C72A since another automotive 
electronics giant also was using it. Luckily I did not choose the 
similar ATMEL AVR part now already obsolete. But still we can no 
longer reduce the cost further since Microchip moves on to promote
Flash based MCU. Even moving to Mask parts do not help since they
are never good at mask parts.

I am a bit curious what are the popular low cost MCUs used in
the industrial application now or a few years down the road. Here
are some wild guess. Please note that they may or may not be so 
popular for the consumer application or hobbyists.

PIC10F200/202/204/206
PIC12F508/509
PIC16F684
PIC16F628A/16F819
PIC18F1220/1320

Any comments or suggestions?
