I really want that upcoming APS-C flagship, but it's it's still looking pretty far away.
If the K-1II ends up having more competent AF tracking performance than the K-1, then more than likely the K-3II replacement will have AF performance as good or even better than the K-1II. The upcoming K-1II reviews on here, Imaging-Resource, & DPR will shed some light on the AF performance. You know that DPR will redo that bike test.
If the reviews point to much better AF performance in the K-1II, I might end up unloading my K-50 bodies & getting a K-3II to hold me off for a while as I wait for the replacement. That will pretty much mean that I'll be staying with Pentax for the long haul.
