3. Hassy is fine because they have such a strong hold on the pro market. For people who need what they offer, they are a compelling solution. That said, I can't imagine ever using their gear in its present form because (i) the camera's still a POS; (ii) the lenses are insanely large and heavy; and (iii) Phocus is a Phucking nightmare to me. (Their lenses are no better or worse than any others in the MF market - just much bigger).
I don't have a dog in this hunt because I don't own a blad, probably will never own a pentax, but I can promise you if you made your living shooting serious work for serious money, the last thing you'd worry about is the weight of the lenses.
I've said it before, but more professional work is shot with a Hasselblad H camera than probably all the other medium format cameras combined.
Now, if pentax up's their game, offers tethering, rentals, has a workable and fast repair center, dealers that know the cameras inside and out, they may make a dent in this already small market, but unless that happens, they are just a "serious" (whatever that means) amateur camera.
