No, the K-3iii will be faster:
K-3iii: 12 fps up to approx. 37 frames (JPG), up to approx. 32 frames (RAW)
KP: 7 fps up to approx. 28 frames (JPG), up to approx. 8 frames (RAW)
The AF function should be a lot better, and not just because of more points. The joystick, for example, should be a very useful feature.
I see the K-3iii as primarily a sports/wildlife camera. Like Tom (@ramseybuckeye) I would want a tilt or flip screen for landscapes, macro and general use. The lack of a tilt or flip screen was a major reason why I sold my K-3 (the other being its high-ISO performance); I found I was nearly always preferring to use the KP.
Personally I would only consider a K-3iii once I felt that I would get enough gain (compared to the KP) to justify the expense for long lens use alone. My feeling at the moment is that I would not while my main long lenses are screw-driven AF (FA*300 f4.5, Sigma 400mm tele macro), which would not be able to take full advantage of the superior AF and burst speed. When I look at it that way, the K-3iii and suitable lens is a pretty expensive proposition: say $A2500 for the body and $A2800 for the DFA 150-450 (when on sale). For that sort of outlay, I would really need to consider the alternatives in other mounts (e.g. secondhand D500 and 200-500).
