The big news for traditionalists & enthusiasts is the new CFV-50 back. I think that will create more of a buzz than most, if not all, of the H-series announcements. The H4D-31 may be priced very well, but what about the rest of the H series lenses? They send the price for a decent "kit" into the stratosphere. Contrast that with the many, many V-system shooters who already have all the affordable V series lenses they need and the bodies they love. Slap on the CFV-50 and they're in hog heaven, with a bigger sensor, for less overall outlay.
I would count myself to this target group. I own a 501/cm with the typical 50/80/150 lenses....long story cut short: it's collecting dust and yes briefly i was happy with the idea of a CFV-50 back. It's still a heck a lot of money but as 50mpx is total overkill for my needs now and for the next 20 years it would be a one time buy for many many years and I could also live with going from square to 3:4 format.
BUT.....
This sensor is still cropping the FoV of the 50,80,150 and I would loose a fair amount at the wide end and a 40/60/120 looks better, but then....buying new glass?? adding up all the costs I probably would be better of with a H4D-40 + 35-90 zoom gaining AF and other stuff.
Seems to me only actractive for V owners that have already glass like 40, 60, 120mm....now if HB would swap my glass 1 for 1.....
nah, it's sad but MF on an expense level as in the film era is gone, this is now commercial/pro territory...
