Thanks, very informative - and very nice of you to keep us informed. Now... could you also watch the seminars?
I don't expect anyone to be able to see the 10% difference in brightness; perhaps in controlled conditions? The big point about that is that the brightness didn't decrease, despite the higher magnification.
Excellent question about AF/tracking. Too bad about the partial answer (but if it's in zone select, the camera should track?)
The AF points display seems similar to the K-1's, and unfortunately the black squares aren't very visible... but let's see on the actual camera.
It's amazing how they worked on basically every aspect of the camera. No wonder it took so long!
But now they have something to reuse in the following models.
