Sony’s New 19200 X 12800 = 247-Megapixel Sensor IMX811-AAQR Implies 108 Megapixels for 35mm Format
As per the specs found at sony-semicon.com, there are both color and monochrome sensors.
However, this technology at present has an aspect ratio of 3:2, at odds with the 4:3 aspect ratio of Phase One, Hasselblad and Fujfilm medium format which all use 4:3 sensor.
Diagonal 64.84 mm (Type 4. 1) CMOS Image Sensor with Square Pixel IMX811-AAQR and IMX811-AAMR
The IMX811-AAMR is a diagonal 64.84 mm (Type 4. 1) CMOS active pixel type image sensor with a square pixel array and 247.04 M effective pixels. This sensor incorporates maximum 24 dB PGA circuit and 16-bit A/D converter.
16-bit digital output makes it possible to readout the signals of 247.04 M effective pixels at high-speed of 5.3 frame/s in all-pixel readout mode.
Doing the math, its 2.81 micron photosites imply that a 4:3 sensor having the same size sensor as a Fujifilm GFX100 II or Hasselblad X2D would be ~182 megapixels, up from the current ~102 megapixels.
Similarly, it implies up to 108 megapixels in a 35mm-format sensor.
It could be a while before this tech appears in a suitable sensor for cameras, since there isn’t even a suitable sensor yet. But the fact that this technology can do 247 megapixels with 2.81 micron photosites with 5 fps readout suggests a bright future for both 35mm and medum format cameras.
Focusing fun: lenses with focus shift and field curvature are already a huge PITA on sensors with 3.76 micron pixels (think Leica APO-Summicron-SL lenses and many others), but dropping that to 2.81 microns is going to put a premium on cameras not doing the stupid shit they are doing today with focusing.

Below, diffraction spot size (Airy Disc diameter) relative to the photosite size of the sensor demands less and less stopping-down to minimize the blur effect relative to the photosite. On a 100MP sensor (35mm format), an f-stop of f/4.5 is needed for similar per-pixel blur effects as with f/5.6 on a 60MP sensor.
