From the Pentax.com press release:
"Coupled with a simple, functional design and the elimination of an aperture ring, this new mechanism considerably improves the camera's operability."
They are talikn about the new "Quick Shift Focus System", however, the sentence also implies, that Pentax is trying to sell the lack of an aperture ring as improved operability. It is even more evident in the German press release:
"Zusammen mit dem Verzicht auf einen Blendenring führt dies zu einem erheblich verbesserten Bedienungskomfort der Kamera"
(Togehter with the renouncement of an aperture ring, this (the "Quick Shift Focus System") leads to considerably improved easo of operation of the camera).
Shall we never again see a new Pentax lens with aperture ring?
