Just speculation, but possible reason they are dragging their feet releasing it is to allow retailers to move the remaining pmd661mkII decks, with the mkIII already absorbing some of the demand. When the 706 hits the streets, any left over 661mkIIs will be dead weight. Just a guess based on marketing decisions like Honda stalling the 2017 CRV for 3 months to allow dealers to move the remaining 4th Gen body styles first.
