See the official discontinued lens list here, even the DFA 55/2.8 SDM and DFA 90/2.8 Macro SR lenses are now included:
So, the Pentax 645 digital lineup is really done, as it is shown and can be confirmed, regardless of any official statement made about this fact. :-( And, those 645 gear of Pentax has become collectors' items now, just like the Q gear.

On the other hand, I wonder if the small MF (cropped down to only 33x44mm) is worth having nowadays, i.e. if even GFX faces harder times?
Given the full frame megapixel monsters, 69 MP, and their modern mirrorless lens designs which manage to resolve that from edge to edge, so that with AI super-resolution on-top, the resolution can be quadrupled to 240 megapixels and still be pixel-to-pixel sharp.
Just saying. Not that I'm advertising 240 MP, that's ridiculously high except maybe for some scientific photography or so. But it is possible with full frame today.
