I'd guess that Microchip may have decided on a different course
for 14-pin offerings, starting with the 16C505 (a 12C509 with a
little more RAM and 6 more I/O's).  I'd guess that if that takes
off they'd likely come up with a similarly-extended 12C671.

OTOH, what I'd sorta like to see would be for MCHIP to introduce
18-pin parts with the built-in oscillator.  This would allow two
more I/O's to be added to existing designs while maintaining pin
compatibility (ever wanted to add a new feature to an existing
product and wished desperately for another I/O pin or two?)  Maybe
it's just my upbringing, but somehow 18 pins seems like the right
size for a micro...
