A new figure does not have to be "Poser Unimesh".  If that was the case then the new Hivewire figure would be pretty much a waste of time since it was built on Poser 12 and  earlier prior technology.  The only thing that Poser Unimesh should bring is the ability to import a figure pose it and then export it and it have the same exact order to the vertexes between the import and export.  And really that is the only thing that 99.999% of people will care about.  What it does inside the program is of little interest to most of you.
