It's another example of the absolutely poor job Pentax has done with marketing/announcing this camera. No "hands-on" previews/reviews (the dpreview one is pitiful and leaves many questions unanswered), conflicting spec sheets, conflicting information on whether auto-DFS is gone or not. (Official response via their chat system - fireworks and nighttime photographers are still screwed and it's "for our own good", but others imply that it seems possible to disable auto-DFS in preview cameras despite Pentax's claims otherwise.)
If there is anything that pisses me off the most, it's the insulting "we're doing this for your own good" attitude. It's why I chose Pentax over Nikon (I bought my first DSLR shortly after the NEF encryption fiasco) back then, and now am regretting that decision. Nikon's NEF encryption shenanigans were heinous in an idealistic way (The only reason to encrypt white balance metadata is to permit you to use the DMCA to sue people who try to produce a third-party RAW converter - they have not done so, but there is no other reason for encrypting white balance data.), but at least proved to not be a technical barrier in any way (dcraw supports it anyway, despite the encryption). In Pentax's case, forcing automatic dark frame subtraction down our throats "for our own good" is insulting. I'm perfectly cable of taking a single dark frame reference for a series of shots and then subtracting it later, I don't need one dark frame reference for every single shot forced on me.
