There are a lot of rumors flying around. I don't know if I believe any of them. But here is some food for thought. If anyone can confirm these details (I'm really searching Intel's site), this would be great info.
- Sony (designer?) and Intel (fab and support logic -- including prototype/reference board?) are behind the newer 12MP CMOS sensor in the APS-C / 1.5x crop size (roughly 24mmx16mm), which is now available in the Nikon D300 and Sony A700.
- Sony and Intel also have a 14MP CMOS sensor in development which will be released soon. Several sites are actually reporting this is more APS-H / 1.25x crop sized (roughly 28x18mm),
- The new Pentax DA* lenses are designed for up to a 1.25x crop, explaining some of the added size (beyond just f-stop).
The current 6/10MP APS-C CCDs in the K100/10D are 1.53x crop. The current, non-Pentax CMOS sensors in some other products (e.g., Canon) that are APS-H size like (yes, I know, APS-H is actually 16:9, but not this sensor which is 3:2) are around 1.27x crop I believe.
If there is a new, commodity CMOS sensor in development at 14MP and it was APS-H / 1.27x crop, then Sunsung-Pentax would have known about it via their engineering "Gold Book" type vendor channels years ago. The design of the DA* series and their 1.25x crop support could be well explained by this then. It's not uncommon for designs to run late, and how the introduction dates line-up on the DA* to the rumors of Pentax's new products make sense.
The 1.27x crop "K20D," with its required 1.25x crop DA* lenses, would command that post-sale premium after-sale return, something that the new Hoya management is probably looking for. Pentax still offers the "K200D" for more cost-conscience buyers, but the "K20D" now gives Hoya more margins, especially for moving that new DA* product stock. It's also far more of a mainstream, commodity product, volume-wise, than the Medium Format (60mmx45mm) 645D would ever be, whlie giving a solid upgrade path to possibly as high as 24MP with a solid ISO in an APS-H sized CMOS sensor.
After all, the 645D started at 18MP, and was also rumored to be possibly 24MP at one point. That was already a far cry from Hasselbad who is at 38MP. The volume for such medium format is already constrained, and Hasselbad would be the call over a solution that is only 45-60% the resolution, regardless of price (after all, why go Medium Format unless for such fidelity?). But now, with a 14MP sensor, offering both full-frame compatibility and a new line of premium DA* lenses, Pentax gets far more volume and those margins to boot. And, again, by moving to APS-H size, instead of sticking with APS-C, while using a CMOS sensor, 24MP should be eventually achievable without too much ISO hit (APS-C is probably more at 18MP).
Now Pentax isn't going to abandon the 1.5x lens crowd altogether, that's where a "sister product" like the "K200D" would fit. You repackage the K10D 10MP CCD sensor, just like the *istD's 6MP CCD sensor was repackaged into the K100D before, with updated SR, the higher-res 900K LCDs like on the D300/A700 (or possibly that's only on the "K20D," and a cheaper, 460K version that is already 2x of today's 230K goes on the "K200D").
I'm sure the fab cost of the 10MP CCD sensor on the K10D is already little more than the 6MP CCD of the K100D now, given the same APS-C die size. In fact, engineering lifecycles are all about reuse and refinement, costs becoming lower, hence the *istD into the K100D with more features, now the K10D into the "K200D" with more features. Some might argue the K100D Super is "too new" to do that too. But the K100D Super is little more than a firmware update (use SR dust reduction, and new firmware so the slot can use the SDM in-lens), so it's just "finishing off" existing 6MP CCD/control stock through mid next-year or whenever they run out (even though sites will still have stock later than that, Pentax won't supply them anymore much sooner). So any "K200D" is ready to take its place.
This strategy makes total sense to me, especially with the 645D being all but officially cancelled and the new DA* lenses supporting up to a 1.25x crop factor. But this is still 100% speculation, I have to admit, but it makes both engineering and marketing sense to me.
