Imaging Resource interviewed a group of Ricoh managers. Here is some of the things they said:
1) Ricohx will continue the 645 medium format line and doesn’t plan to make a mirrorless medium format camera
2) Ricoh has no plan to launch a new mirrorless system camera
3) Ricoh also made this somehow unexpected statement:
Currently, mirrorless is a newcomer, so of course many users are very interested in the new systems, they want to use [them]. But after one or two years, some users who changed their system from DSLR to mirrorless come back to the DSLR again.
So the DSLR market is currently decreasing a little bit, but one year or two years or three years later, it will [begin] getting higher.
I really cannot believe this is true :)
