Hello,
I personally test the H6D-100c in photokina, my visit to Hasselblad studio was focused around the new H6 system, live view, display, video, and about the pixel quality as the new 100mpix pixels are smaller in size than the 50mpix one.
I was astonished by the quality of the shot made at ISO 12800 without flash and underexposed to check the noise in shadows etc.

Here's a little video I've made live with Facebook while I was there...
About the use with technical camera as I'm interested in, they said me the camera have all the connections needed and they made agreement and sharing od technology around the interface with ALPA that have the stand in front, now is possible to use H lens on ALPA tech camera and control them, also the back is powered from the ALPA camera and no need of external battery pack.
Substantially, for technical use now the H6D-100 have the same use and support (if not better) than the concurrence, and with some restriction the HTS 1,5 can stand, avoiding the use of tech camera in many situations.
I was very very pleased to see Hasselblad in so good shape and health (apparently), I see also P1 stand and tested the IQ1-100
the phase stand was very low profile in comparison, they have no english docs about their product.
Returning to Hasselblad, as I own an H5D-50c WiFi I didn't see a big step forward between, and I have decided to stay with 50CMOS that in all aspects for my needs is what I need, waiting the market stabilises, price drops as new products are arriving and improving in few Years.
Best regards, Domenico.
