>>3241899>A7RIII or D850There is a couple of issues with this.
The 42MP sensor design is owned by the image division, and Nikon wasn't allowed to purchase it from the sensor division. The chance for Pentax to acquire it is slim to none.
The 46MP sensor design is in all likelihood owned by Nikon. If that is true then Pentax has 0 chance of getting it.
The second problem with the 46MP sensor is the limited quantity of it, so even if it was available to Pentax, Nikon would be able to bid more money on them.
My guess is the sensor will be 36MP.
