An f/1 lens is a showcase lens. I don't think that there's a business case around this alone that could fly.

Thanks for correcting my typo ;-)
The LCD is likely a touch screen - it looks the same as the one in the GR III. Which means the sensor above it would not merely turn off the annoying LCD light (good point there), but also disable the touchscreen so you won't change settings with your nose.
Despite the touch screen, the joystick is mandatory in such a camera; you cannot e.g. operate a touch screen with gloves, and this isn't made only for ideal weather conditions.
And... it looks like the AF module will be different, likely with better coverage; the joystick might also indicate more AF points.
Let's sit tight and wait to see to which extent this camera will address Pentax' performance issue.
Off topic:
I was responding to a forum question about the Sigma 50-150mm F2.8 MkII (non OS) lens in the Pentax mount (which I had) an went to link the PZ review of the lens ...... only to find it "not there" under the Pentax K mount section.
I'm certain PZ tested the lens, as it was compared closely to the Pentax 50-135mm version.
Does PZ/OL ever compare lenses closely? Or did you just remember it that way? PZ/OL tested the Sigma 50-150mm f2.8 OS and mentioned the Tokina 50-135mm f2.8 briefly.
The guys also tested the old 50-150/2.8 in Nikon mount.
