Michael,
I hope this makes sense.
When the FX3 decoders were announced I contacted Digitrax. My question was will there be a FX3 decoder available for a Nscale Atlas U25B locomotive soon. I wanted transponding for these engines.
I was told that during 2002 all decoders except the DN121 and the DH121 were going to be replaced with decoders that had the FX3 features. The order of replacement would most like be in order of popularity.
If this is the case we can look forward to many of the current decoders discontinued for newer FX3 models this year.
Just thought everybody would like to know that there are more new FX3 decoders are in the pipeline.

I agree, it's not clear cut. Some decoders do not support everything other decoders that are in the same class support. But the individual decoder XML files can take care of that.
As I see it (for decoders produced in 1998 and later):
Standard decoders:
DH-120
DH-121
DN-121
DN-121IP
DZ-120
DH140U is a multi format decoder with BEMF, but on DCC it's just a standard decoder with BEMF
Configurable Strobe (CS) with BEMF & transponding
DN-122K2
DZ-121
FX without BEMF nor transponding
DG-380
DG-580
DH-140
DH-150A & K
DH-83FX
DN-140
DN-144K
DN-145K
DN-146A
DN-147A
DN-148K
FX with BEMF & transponding
DH-142
DN-141E2
DN-141K2
DN-142
DN-149K2
FX3
DG-383AR
DG-583AR
DG-583S
DH-163A0
DH-163D
DH-163IP
DH-163K0
DH-163L0
DN-163A0
DN-163A1
DN-163K0a
DZ-143
Various cable options not shown, such as P, PS, AT... They're just different cabling connected to the same base decoder.

Thanks for the detailed comments!
I put together the original Digitrax definitions, along with some
help from blameless others, and I'm happy to agree that I probably
didn't get all the details right.
I'm on a business trip, so my time is a little limited for the next
week and I can't get to my layout, but I'm happy to work on this type
of thing while sitting on airplanes.
The basic underlying idea was that decoder manufacturers would have
various software/firmware versions that they'd use to make multiple
decoders. That same firmware might be installed on various PC
formfactors, with various numbers of output transistors for
functions, but would have the same CVs in each case.
Those firmware sets are the basis for the "family" idea. A file,
which defines a family, also contains the list of decoders that
belong to that family.
So you can see how this would go wrong: I'd code something based on
the info I could get from the web. To the unpolished eye, perhaps
assisted by the "system" of decoder names, other models would look
like they had the same features, hence belonged to the same family,
so I'd add their names to that file. But it was easy to get this
wrong.
So, as a start, what should be the names of the various types of
Digitrax decoders? At one point I based the names on the Digitrax
function naming" FX, CS (configurable strobe), STD and STD*, plus
the new FX3. But that now doesn't seem to be the right approach,
because BEMF and perhaps other functions appear in different
combinations.
