Hmm, that's interesting. I wondered why they did not seal the body side but when taking a look at my canon body, I can see what it is difficult (screws and such). Sorry for littering the list with too many posts on this subject, like an obsessed sealing maniac :-). But looking at Pentax mount surface, I do not see how they could put an O ring on the mounting surface as, unlike Canon, contacts are all on the mounting surface. So the seal could be circumferential, such as just behind the mounting surface. This will require an extension collar on the lens side. When gazing at the picture of the K10D with a lens attached, mounting surface does not appear visible (lens looks like attached close to body surface). If that's the case, as someone pointed out, only new lenses are sealed (at least at the mount). We'll see it soon.
