I may be alone in this but I'm actually in favor of this decision by Hasselblad. My understanding is that with existing shutters, the HC/HCD lenses on the H6 will do 1/1000th of a second. I'm actively pushing my local dealer & rental shop to not reshutter their lenses, just get 3-4 new, higher shutter speed lenses and charge $10/day more for them. They've got literally 1 of each (shy the 300 which they don't carry) but 2 of the 50-110mm and 150mm. I've had times when the lens I want is out with the other shooter, so this works in my favor. With the X1D, I think there'll be more folks looking at the H glass as things like the 24 & 28mm aren't going to be done as new primes.
My technical reason for not reshuttering is that if I'm putting this lens in front of the 100mp chip, I want to be damn sure it's accurate and sharp, having been qualified by Hasselblad to showcase their latest back. We all know that Sony will do a higher MP chip (Phase says as much with their 'beyond 100mp' resolution qualification on the latest glass). From the rental/dealer perspective, I wouldn't want to have a customer coming back to me with issues in their shoot that could be blamed on the lens shutter - if you need to go faster, get the new version of the lens.
Personally, I'd love to pick up a lens or two that are perfect, but limited to 1/800th. Lenses I think the 1/2000th would be helpful in are the 35-90, 80, 100 for standard users, and maybe the 150/210 for folks like me who shoot sports with their Hass.
