I did not see anything on that list about PCM voices. What I did see was Mega-Voices and being able to load your own stereo samples. I don't think the KN7000 allowed one to load samples did it? I have not heard anything with better voices than the current guitar Mega-voices. Adding the other Mega-voices with super-articulation ought to be stunning.
But, then again, is what we are seeing on this specs list the actual and final version? Wait and see, I would guess.
