You may disagree, but you are not the market. For me, there is no reason too buy anything from Pentax is no higher than 36Mpixel is offered. Simple, if you don't need more than 24Mp, just keep using the KP you already own, but that's not business case for Pentax.

Originally posted by jersey It seems that making FF with new prism tech will be prohibitively expensive.
If there are issues with a larger prism on the K1, I guess it's not because of the cost, but because of the geometry of the K mount / mirror box. I remember they had to re-engineer the mirror mechanism in the K1 because the classic apsc design wouldn't fit. On the K3 III they had FF headroom to play with, on the K1 there's no such headroom.
