Spot on. It shows that Pentax have no plans for discontinue them in the near future....
My guess is that the Japan made FA Limteds will in the future reach astronomical prices on e-bay. Particularly the early batches; those that came with different color leather lens bags: A brown for the 43mm, Green (77mm), and red (31mm)....
