In this case my imagination is that Hasselblad does not need to look too much further, in fact, make a camera like SONY NEX-7 (as example, or like those m4/3 cameras) - that can accept a larger range of lenses BUT
with a larger sensor, and then let the user produce result by their creativity. I use my SONY NEX-7 like a self-contained digital backs on many shots (OK, mostly for fun), but then if it is a 36X48 CMOS sensor that can capture excellent still, 4K video (in case needed), all the possible setting on a single camera body - and can accept proprietary lenses as well as market lenses, it would be much much bigger business and mor eprofitable than a H platform carried over decades of old medium format set up.
The photogrpahy world has contantly change over time, with the resolution of today's best sensor, I am using iPhone to do what i did before with film P&S candid, my G12 is more like the old day Contax T3 for serious P&S candid, then my NEX-7 is working like my old Leica M, my Cnaon and Nikon FF DSLR is doing the job used to be medium format, and my digital backs (Phase, Hasselblad and Sinar) - although still on medium format body - is like those large format cameras of the old day, I can't imagine I would need a camera with even larger sensor if digital stitching continue to evolve.
I do no think Hasselblad can survive long time or even a decade as a medium format only supplier and I don't think a H5D will help change that. But a newer camera concept to approach to greater audience will do.
Sorry. Maybe I'm nor making myself very clear but I am talking about the Camera as a whole and not just when the back is on a view camera. I use the back on the body and on the view camera. I would like to use those tools as would many on the body and on the view camera.
