I agree, but not yet.  These PICs have to become real first, then they have
to make it thru distribution to become available, then a bunch of free code
and other support has to become available for them on the web before they
become a superset of the 16F628.  Remember the fiasco about the 18F452 being
available "in 3 months" for almost a year, and what about the 16F877A?
Microchip has a credibility problem with release dates of future chips.

Not credible information.

Perhaps, as I don't give much chance of the PBK coming out anytime soon
either, especially seeing how this committee thing is going.  Whoever said
"two minds is better than one" must have been billing for the time, not
paying for it.

I think a little more flexibility than just the 18F series is worth it.  The
dilemma you mentioned can be easily solved by deciding whether the chip
plugged in is more than 18 pins or not.  It does this by detecting the
protection diode to Vdd on pin 10.  See http://www.embedinc.com/pic/prog.pdf
and look at what Q5 and Q4 are doing.
