Here's another example of moire from the K-5 IIs.
Sharpness freaks need to realize that AA filters serve a very useful purpose.

This is a way of looking at it, that is only voiced by those that do not have a K5IIs, and seem to want to write it off. Virtually everyone that has bought a K5IIs, and that includes myself, is really very positive about the IQ results, and that has nothing to do with being a sharpness freak.
Moiré véry seldomly occurs, and is considered a none-issue in everyday shooting by almost all the K5IIs adopters, and that's not because they are closing their eyes to it. And I have four very sharp Zeiss primes, so I should be in the moiré danger zone.
By no means do I want to write the K-5IIs off. I was merely pointing out that there is sometimes a price to be paid for not having an AA filter. Although many may consider moire to be a non-issue with the K-5IIs, I would say that is because they are not looking for it very hard. It is almost certainly present in more of their images than they would like to believe. (How many had noticed it in DPR's sample?) Whether moire is critical in every instance is a different matter, but when it is, eliminating it can be very challenging.
I am a K-5 owner. I deal with image softness due to the AA filter by applying deconvolution/deblurring in the raw stage, and I am quite satisfied with the level of sharpness that I am getting. Ultimate sharpness is not my photographic goal. Sharp enough is good enough for me.
Fair enough, and the K5 produces stunning images with proper deblurring, but again, in normal shooting really, moiré is a non-issue. For every image that people upload with moiré, there are hundreds without a trace of it. It simply seldom occurs. You only find that out when you start using the K5IIs day in day out. And it's not because people aren't looking hard enough. It's a good move on Pentax' side to release the K5IIs, less post processing all-round, and negligible downsides in real use. The K5 is also a great camera, but it's about real, everyday use, so people who don't own a K5IIs (and are convinced it is not an upgrade to the existing K5 IQ wise), should simply take some reserve in criticizing it, the growing collection of moiré induced images on the web should be seen as what they are, a véry small percentage of the K5IIs output.

Chris,
I do not question the fact that the K-5IIs is sharper than the K-5 or that this represents an improvement in IQ. I merely want people to be aware that there is a downside to having no AA filter. I think that is unarguable. I also want people to think about how much sharpness right out of the camera they really need. Sharpness is only one element of a photograph, and rarely is it the most important one.
