Actually we could get an idea of what will happen by a. listening to the camera maker and b. considering the exact opposite of those doom and gloom posts.
Fact: the other brands can sell a crop camera for as much as $2000. Fact #2: the K-3 II was launched for $1100.
The K-3 II's replacement will be somewhere in between... we would be able to guess after the first leaks about its specifications, if the price won't be leaked first (quite likely IMO).
If the DSLR market will fade (nowhere with the speed MILC fans are dreaming of, since a decade ago) then the moment of launching a high-end APS-C DSLR is asap.
The KP is not the APS-C flagship. Ricoh Imaging is "researching" i.e. working on a K-3 II successor.
Mirrorless is less relevant than its fans want us to believe.
