It's not just the motor, they redesigned the entire focusing group and made it over 90% lighter. Which unfortunately suggests the PLM would not deliver the same blazingly fast results with heavier lens elements used in faster aperture lenses.

It's impressive nonetheless.
Which then opens the question of which lenses will be upgraded soonest. If the K-70 is pointing the direction I believe it is, Pentax and Canikon are all going to higher ISO, rather than constant wide aperture long lenses, to capture sports. Those who use wide aperture for DoF may not be moved by less noise and/or faster focusing, so those lenses could easily be updated later, after Pentax has more experience with these new technologies.
