20 years is a *long* time.  I bet there are a lot fewer 4 bit processors 
used now than there were even just 10 years ago.  I seem to recall a 
forecast somewhere that did show 8 bit MCUs dropping in volume over the 
years.  But I doubt the 32 bit units will be edged out by 64 or 128 bit 
processors.  Unless the embedded apps have to go 128 bits to be able to 
address the on chip memory.  lol
