Red Dot Forum had another camera talk on YT, this time about Q3 Monochrom. They also explain the reason for the lack of PDAF (@44:42).

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

I really like RDF, but I think they are speculating here. 

I am also speculating, but I genuinely believe that Leica just buy this sensor: https://www.sony-semicon.com/files/62/pdf/p-13_IMX455AQK_BQK_ALK_Flyer.pdf

Sony simply does not produce a monochrome variant with pdaf pixels. End of story.

Both @jonoslack and RDF got the same information from Leica. This is not speculation.

Sony does not publish spec sheets for customers' sensor designs. The fact that there is no spec sheet with monochrome and PDAFs does not mean that Sony cannot make them. If you listen to the RDF explanation of how OSPDAF is implemented, you will understand that it is possible to implement OSPDAF using a monochrome sensor.

P.S.: X2D and GFX100 use the "same" sensor, but different OSPDAF implementations (number of rows and row locations).
