My guess is a high-end APS to replace the K-3 and K-3 II and a mid-range APS to replace the K-70.
The high-end APS will probably not be named K-3 III, and should have improved AF tracking capabilities (using a better CPU, maybe the PRIME IV from K-1 or a dual CPU approach as some other competitors).
The mid-range APS will probably be very similar to the K-70. It may receive the AF module and the light metering of the K-3: the current TTL 77 metering appeared in the high-end APS in 2009 with the K-7 and was taken by the mid-range APS three years later with the K-30; four years after the K-3 is the right time to expand its use.
2018 will probably be a more critical year for Pentax: 645z will need a replacement, and the K-1 too, but I doubt they will be able to do both.
