Here is the recap from a recent marketing event in Taipei with Ricoh executives:
New Pentax K-1 Mark III camera is still under development.
The Pentax film camera project is in good progress but further details will not be disclosed. Collaboration with other film product manufacturers will be made.
Unlikely that the Pentax Q system will be brought back to life.
The 645 system is at the end of the development cycle.
Mirrorless is not a viable option for Pentax.
New Pentax DFA* wide angle lens(es) and replacement of the DA* 50-135mm are being considered.
Also: Ricoh will not be participating in the next 2024 CP+ show (February 22 – 25), but I think we can expect a new Ricoh GR camera to be announced in early 2024.
