Well, the main problem for the K3 replacement is the lack of a new sensor offer. We've been stuck with the the base 24 mp Sony sensor since ~2011; there have been improvements, but they were mainly for mirrorless cameras (on-sensor PDAF for example). This, combined with the rapid decline of the camera market, means you simply can't keep up the "new camera every 1-2 year" cycle of the 2000s.
