What I meant with "ordinary 645-system with central shutter" was that it is ordinary EXCEPT for the central shutter, I have no idea how reliable it is but I would prefer it to the gigantic, loud and vibration-prone fp-shutters anytime. I have no doubt that it is electronically controlled and therefore much more precise than the old mechanical Compur! But the electronics and the extra features of the H-system are not my problem, the integration of the whole system is well made and much better than the other 645-systems - propably a secret of it's success!? I'm not talking about all changes made in contrast to the old V-system, I'm not a traditionalist, it was a huge opportunity to change basic problems of this system. I'm talking about the unnecessary changes the fate of the skilled craftsmen in Göteborg and the result, especially in materials (outer plastic shell, the inner sheet-steel-construction of the viewfinder, buttons...). That was always the first thing anybody noticed when handling a Hasselblad 200/500 in comparison to any other system of the last decades - not only the feeling, but also the actual robustness after decades (yes, I've seen broken plastic-camera-shells myself and know about mechanical properties)! Modern plastics have many advantages but it's not the perfect choice for hq-camera-systems! No, the mechanical design/material/assembly isn't better than a Mamiya anymore, they can be lucky that Mamiya and the other (cheaper) MF-systems had so much trouble integrating digital technology - build-quality isn't an argument anymore for Hasselblad in favor of the others (like it was for 50 years)!
It's like the discussion about lenses, they're not actually bad (in fact, I find every comparison with 35mm-systems or 10MP-Leica ridiculous), they're just not as unique and designed/manufactured to the uppermost standards anymore - you can find the same properties and performance with Mamiya, too. But Hasselblad is the upper-end, if you're not satisfied with certain details of those >>10k$-systems, you're in trouble!
Maybe you're seeing it from an entirely different perspective, but I think diversity is important and we don't need another "me too", "works fine for most users" and it makes my heart bleed that a system like the Hy6 seems to disappear (not because of high-manufacturing costs or missing buyers!) and other big names become "exchangeable". I've seen it with other industries, they slip slowly into mediocracy, cut costs where consumers don't seem to bother. But after years of working this way, people start to realize what they lost - when it's already too late!
