One problem would be that a 16mp sensor would be seen as something from the past. A megapixel count that suits smartphones. I don't agree with that, since 16mp is plenty for a good print, but most people think maybe that it isn't.
To get enough volume for a custom designed sensor. Well make as many of your camera's suitable to work with that sensor, starting from the same wafer.
From the same wafer one could design:
- Aps-c 16mp
- Aps-h 25mp
- fullframe 36mp
- MF for 645 with 60,5mp (44x33mm)
- MF for 645 with 72mp (48x36mm)
Same pixelsize, just on different sensor sizes.
I'm so lucky that I have no idea if it works like that. But Ricoh-Imaging would have his own line of sensors (made by Sony).
For fun one can calculate how many sensors one can cut from a wafer.
