I'm not sure what the down side is to a 12MP high ISO sensor. OK my screen, which is huge compared to what most are using is 2560x1440 that's a little less than 4k, so the idea that 12 Mp is only for screens is false. Second, I've sold 10 Mp images at 20x30 inches, so the idea that you need more than 12 Mp for printing, is also false. It really depends on the image. every image is going to favour a subset of the population. From a marketing standpoint there's no evidence that the segment of the market that prefer 16 MP images is larger or smaller than those who prefer prints from 36 MP images and there's some evidence that they can't even tell the difference.
The big drawback to Pentax and APS-c in general is noise in low light. A camera that could be pulled out in low light situations would be the perfect companion to a K-3. Plus it would give folks "more control of DoF." for those for whom that is critical.
To be sure it wouldn't satisfy those who want higher resolution but having a camera that would give me a stop or two over everyone else's low light performance including all existing FFs beside the D4s would be awesome.
But to me, higher resolution has always been the weakest link of the FF argument. There have been so many inconclusive demonstrations, that at this point I think it's safe to say higher resolution does not lead to more appreciation of a photographers images, except in a very small portion of the population. It's important for some but certainly not all, and many can't choose which image they like more when choosing between 36 MP and 16 Mp images. And really I like my K-3 more for the smaller AF point and more accurate AF than for the increase in resolution, for which I've seen no noticeable difference.
I tend to think 2 stops is worth investigating, 3 stops is worth buying, a 3 stop noise difference with corresponding maintenance of resolution at high ISO would be simply awesome. Especially with preliminary suggestions indicating that DR is maintained at high ISO, that in itself is a huge deal.
To me, just the idea that you could get to 2400 ISO and maintain you DR is in itself ground breaking and because the sensor is in the A7s, there currently isn't a DSLR using it. I mean, how unique is that?
I have enough money sitting in my 645D account, I could pre-order this camera were Pentax to release it. But I tend to see things differently enough that just the fact that I'd buy it means it isn't going to happen. Call it the normhead kiss of death. I'm just more influenced by what I see in real life than by the hype I read everywhere, which essentially represents what camera manufacturers have to sell as a lot more desirable than it often is. They have to sell what they have, but i don't have to like what they have.
A 12Mp low light sensor would get Pentax some of my money as it would be purchased instead of a second hand 645D, which would make them nothing, but , I'm one guy, and one guy is worth zilch to any modern corporation.
