Hi folks, I also tracking Pentax cameras as consider buying their dSLR in future.
Here you can find more sample photos from Dubai:

And also some video of presentation and how photo session took place.
Although everything is on Russian you can use tool like this http://babelfish.altavista.com/tr if interested in reading texts or ask me if have any difficulties with this page.

BTW I think that Pentax shouldn't put so much resolution in their sensor, I would prefer seeing less resolution but sharper images and less noise...
