Quite simply, I vote to maintain the emphasis on software.  Figures will come and go.

That's not to make light, at all, of the "accessory" angle or the content "conundrum" but that's exactly what it is.

Who wants a car that has a bad ass radio, full gps, the interior bells and whistles but has an engine that needs fine tuning, tires that are worn and a frame that could be stronger?  I know what I want.  I can always put my own radio and other amenities in there myself.

I won't touch the other discussion except to say that some of the Genesis style abilities, inside Poser could be pythonically solved because that speaks, to me, more of streamlining the system to make it happen, like more efficient morph saving, swapping UVs (which could be swapping geometries there or injecting some kind of UVS file into a temporary geometry), making geometry switching tighter and on the fly for grafting.  HD morphs are about opening up the pixar SD spec more.  And yes, some of that would have to be tuning in other ways, on the program level.
