This is the rumor I received:
“It will look like the Leicaflex 18X24 prototype.
Of course without mirror or the film lever and so on.
It will be a VERY small system camera, but there will be a big battery grip you can use, if you want.
The AF is very special, moving chip, the phase AF is ON the main sensor.
Only in black, 21 mp, 2fps, native ISO from 50 to 6400.
Full magnesium.
Price: body only 3200 EUR.
Will start with 3(!) pancakes, 2 primes, 2 zooms.”
FYI: this is how the Leicaflex 18X24 prototype looks like – as far as I know, only one camera was produced:
