Since this was said in public by Leica leadership here in London in public (not formally announced) in conversation I feel I can write this.
As I previously predicted we will not see the in house Leica designed sensor in the M12. It will come in 4 or 5 years in the next generation.
When it does come it will be a very fast sensor. The goal of this is to have an electronic shutter. The reason for this is to make room inside the camera for other features. It wasn't said specifically but I beleive that this is to make room for the number one requested new feature IBIS.
All of this is directly from the horses mouth, so speculation about these things shouldn't be needed going forward.
There was also a very interesting statement made as to why Leica is find it necessary to find a new sensor provider. I will post about this later, but it should remove some myths regarding some other brands..
