Yeah but polyphonic aftertouch is irrelevant to "piano" sounds - once the hammer has struck the strings you can't make anything else happen to the tone by trying to perform "aftertouch" on the keys.
PolyAT is much more useful for things like evolving synth pads or adding vibrato to brass/woodwind style sounds - which seldom require 88 keys, but then to fit fine within a few octaves.
So whilst an M4000D certainly would not compete with the Kurzweil MIDIboard or new VAX77 for offering the ultimate versatility as a MIDI controller with PolyAT, I suspect it will actually be a very musically useful one for the majority of applications you'd have for PolyAT.
