I looked at what he said - the "CFO of Ricoh" was just made up (to avoid stronger words which would be entirely appropriate).
Instead, we have an official press release:
"Notice Regarding Delivery Schedule of Medium Format Digital SLR Camera “PENTAX 645Z”
Thank you for your patronage of our products. Regarding the “PENTAX 645Z”
scheduled to be released on June 27, 2014,
we have received a reservation that greatly exceeds the initial assumption. It may take some time before delivery.
We sincerely apologize for any inconvenience caused to customers waiting for this product."

Of course, I can offer no precise numbers except the initial production volume of 400 units per month.
