Pentax 67D is not a good idea.
Hoya says that they have no plans about it. And it is a very clever position.
What is 67 film camera body?
It is a "container" for 56x70 mm film frame. And "receiver" for 67 lenses without auto-focus.
645D is a receiver for non-auto-focus 67 lenses too - through adapter 67/645.
And 645D is an universal container of 44x33 mm sensor for ALL the lenses, not only for Pentax 645 or 67, but for different other (through adapters).
If you really need 5:4 format instead 4:3 format in 645D - you can cut a little. Imagine that you have 33x41.25 mm sensor with 5440x6800 = 37 Mp in 645D for your 67 lenses. Right now.
It would be better to make next step - "645D II" with Kodak KAF 50100 in it.
50 Mp, sensor size 49.1x36.8 mm, crop-factor is only 1.14 from 56x41.5 mm "full-frame of 645 format".
And everybody knows, that new lenses DFA 55/2.8 and DFA 25/4.0 - both are "full-frame", because they cover 56x41.5 mm frame. It means that may be in future - "645D III" will have a sensor size 56x41.5 mm nearly.
What is the difference between such "645D III" and your "67D" ???
It`s much more better for Hoya to produce "auto-focus 645 digital camera + universal digital back for ALL the lenses" - in ONE body, not in two different bodies.
There is no need of special digital 67 body for using 67 lenses now. There is only one reason for existing of such camera - a habitual work-flow with 67 bodies and accessories. But this reason is not enough for producing such cameras.
