Cool!
But (as I may have mentioned once or twice), to my mind the link betwixt 000 & D came much later - 1976, to be exact, with the birth of the M body (AKA 0000); slightly wider lower bout than a D (1/8", IIRC), 000 narrow-waist shape, and 000 depth.
Almost all the volume of a D with the tonal balance and most of the comfort of a 000; equally at home flatpicked, finger-picked, or strummed.
As to new ideas vs. old, I do not find myself drawn to any Martins that fall outside of the traditional 5-4-3-2-1-0-00-000/OM-M/000-D, 15-16-18-21-28-35-36-38-41-42-45 nomenclature.
I wish Chris would have played a little on each to whet our appetites a bit more, though.
