I am a newbie here, but not at other places. And in other fields that interest me, I know a few people with actual insider information.
From my experience, I can tell you that if someone actually wants to leak inside info, he/she will be most careful to hide his/her identity to avoid problems with NDA. In that regard, I would say it fits to see that Wendy won't give any hint about her/his real identity.
Besides, and in my humble opinion, her posts look credible. We will see in short whether they hold water or not. But my instict says "yes".
BTW, I don't know how many of you guys can read Spanish. For those who can, there is a webpage from a Spanish well known photographer, Valentín Sama, called
DSLR Magazine. He's extremely well informed, and he's under NDA with Pentax regarding the K20 (since November 2007). No secret here: he posted it.
If you look at his post on upcoming products for PMA 08 (
here), and based on the drawings from recently disclosed Pentax patents, an on the recently leaked specs of the Samsung GX-20, he speaks openly about
Live View ON THE VIEWFINDER.
There is actually a very little jump to make from that to suggest that the rumoured 720 p/H264 video is more than a possibility in the K20HD. And I happily do that jump, as I signed no NDA whatsoever. In fact, I just updated the little
article I posted about the rumoured specs of the K20HD in my blog with this very piece of info, that I consider overlooked thus far.
