A PetaxForum member compiled a list of all Pentax interviews going all the way back to 2006:

The latest Pentax 645D, Pentax K-3 II and Pentax K-S2 photographic dynamic range and other sensor measurements were published at PhotonsToPhotos – you can now create comparisons with other camera models (below: FujiFilm GFX 50S vs. Hasselblad X1D-50c vs. Pentax 645D and Pentax 645D vs. Pentax 645Z):

After the GR III announcement at Photokina, there is still one more registered but not yet officially announced Ricoh camera: Ricoh’s R02010 is expected to expect the Pentax brand new SLR because Bluetooth is not described in the GR III developed and announced last month (although Bluetooth may be added in the product version).

Ricoh has a new series of articles called “Make the most of your PENTAX camera“. The first two articles are: How to optimize focusing accuracy with large-aperture lenses The PENTAX Hyper Control system: A quick, effortless way to find the optimum exposure settings
