Thanks for the clarification on live view on the V system.
Concerning the Pentax 645z and pricing, each time I've heard something from someone inside Hasselblad (or Leaf or Phase One) the story is that they've heard that the 645z don't sell that much, and that it's so cheap that they're either making very little money per unit or even losing money per unit. If it's true, if it's false but they believe it's true or if it's just marketing strategy towards customers I don't know.
As far as I can see the difference to a flagship 135 DSLR is the sensor, which should be more expensive, and the lower volumes. I think the sensor difference is widely exaggerated, sure they are expensive but it's like $1-2k extra, and if we just had to pay for the extra sensor cost MF cameras would be very affordable. Lower volumes must be the main reason for the high cost. To make a high volume product you need to commit at an early stage to make large volumes and that costs a lot of money, which I don't think Hassy have. You also need to take a large risk and assume that you can sell that large volume you intend to manufacture. I would guess that the current manufacturing facilities don't have the capacity to make large volumes so they would probably need to start manufacture in Thailand or similar countries too to be able to make volumes and keep down the cost, and starting up a new factory there is not a small thing, especially for a company that hasn't done it before.
The CFV-50c is some sort of special case, but I think one should see it as a spinoff product on the H5D-50c (ie the H5 sales pays the development costs), and Hassy wants to keep some maintenance of the V system for the sake of the brand.
Considering the state of the current products I think we can safely say that what Hasselblad wants to do in the MF space is to make money on what they already got with the least amount of new development. While there's nothing wrong with the backs and their software in terms of image quality, it's clear that not much development effort has been put into it to keep up with the latest popular features, they've had to prioritize heavily and arguably they have made better choice for photographers than Phase One which indeed have more modern backs and software, but instead a less capable body.
I would not expect any revolutionary product coming in the MF segment, other than what can be provided through third-party sensors, the Sony CMOS backs are pretty revolutionary in some senses. Considering the luxury products I think/hope it will continue as before as side projects to the main MF line, although they will probably try harder to sell some H and V units to enthusiasts, the odd product placement shown in another recent thread could be credited to that.
Photo enthusiasts and professionals don't necessarily need all the latest features, it's more important what result you can get. As a tech cam shooter always shooting from a tripod I certainly don't need much features from the back, and I can live with a CCD. The resulting image quality is what counts. However, to make that huge selling hit I think CMOS feature set is necessary, to be popular among the masses it needs to work close to a DSLR, as that is what people are used to today, today potential MF photographers rarely come from film like they did 10 years ago. The 645z is in the best position for this, but lags on studio pro features still. As a tech cam shooter I think it's unfortunate that they discontinued the CFV-50 rather than running in parallel (like H5D-50 and H5D-50c), but I guess they thought that the CCD version won't sell to enthusiasts due to lack of high ISO and live view, and maybe they're right.
