I think Hasselblad will have to be more inventive than any of us are here to really make a mark.
For example, I doubt any of us would have predicted the True Focus/APL innovation.
They have gone both ways in past ... a relatively incremental but costly change between the H3D and H3D-II cameras ... and a more inventive change between the H3D/H3D-II and the H4D with TF and other useful stuff including the double res LCD.
IMO, they will have to add more value to both the cameras and user experience to jog the market.
One thing that would instill more confidence would be an included combined 2 year all inclusive, 5 year depot warranty (with a small deductible) that is transferable. 5 years of warranty total would vastly improve trust and a sense of value in these uncertain economic times ... and improve the perceived re-sale value a lot.
The other thing that would garner my attention would be improvements to the current system while adding a new complimentary body with an H mount that could serve as a replacement for 35mm systems. Drop the H4 or 5 camera with 31 and 40 sensor, offering only a more studio based 60, 80 single shot and the 50/200 meg Multi-Shot ... and produce a smaller, faster HX-1 (mirror-less?) dual shutter body, higher ISO (a good 3200 or 6400 is enough for me) using a smaller 40 or 50 meg CMOS sensor, Live View, TF ... did I mention fast?
One set of lenses to full-fill many more tasks rather than two complete lenses systems. The 50, 80, 100 and 150 lenses would serve to keep it all relatively small ... and maybe add a smaller HX WA and a longer "bird" lens options from Fuji
I was struck by the above idea when Leica offered the full function H to S adapter ... in theory, if Leica produces a faster CMOS based S3 with LV, increased ISO performance, better AF as rumored, it will start to fill that function. As I've used the S2 over the past year or so, my 35mm system has fallen in use dramatically. The next step could eliminate it entirely, with any slack being taken up by the more innovative smaller cameras coming on strong.
