They are very proud of the fact that all the future devices they were showing use compatible pinouts to old parts. In my book this is more important than keeping things internally the same, because it allows me to keep the PCB the same even when upgrading to a new family chip (ie, 18C from 16C). With an upward-compatible C compiler like HiTech's, it becomes a secretarial-type task to make sure all the registers are used identically rather than requiring thinking about banking.

So more than likely they will have the same NC pins on the 44pin PLCC packages. The adapter sold by Digikey is hardwired.
