Soft synths can be made do to whatever you want :-)
Release velocity adds a new expression possibility
that could be interesting in particular for monophonic
synths. And I'm contemplating writing one...

All of this can be done in software - it's modification
and reduction of existing data rather than ensuring its
availability.

Another useful feature (already mentioned by another poster)
would be a number of digital rotary encoders, and if you have
any spare AD channels, analog control inputs.

About afterpressure, my SL880 only has this for the
entire keyboard, not per key. It uses a pressure
sensor strip running along the entire length, and
is quite difficult to use as it is. Don't know if
this is due to the sensor being too primitive, or
to the processing in the SL880's tiny controller.
