Knowing that this policy is liked by most back users as it gives the impression of highlight recovery, it would be surprising if Phaseone had decided to go back to a stricter definition of ISO.
On the article, interesting and well written, thanks Mark.
Now, one detail that made me smile... as usual we are now finding out that the supposedly perfect shadows of the P65+ were in fact not that clean. I wonder if the consequent 6 stops additional DR claim still applies to the P65+, or whether is has been automatically re-mapped to the IQ180?
Cheers,

Bernard,
Potentially, an 80mp DB with a binning capability that produces clean 20mp images at high ISO would be a tremendous selling point.
The larger sensor would still have a DoF
disadvantage when an extended DoF is desired, but in binned mode it should have a resolution advantage when a shallow DoF is desired, and when the lens is used at its sharpest aperture, provided too much noise doesn't get in the way.
One thing that's not clear to me is whether the sensor+ mode is available at all ISOs. If it is, is there any DR and noise advantage at low ISOs?
The increase from 60mp to 80mp might sound like a lot, but it's really no different from an increase from 6mp to 8mp. When I upgraded my Canon 6mp D60 to the 8mp 20D some years ago, I didn't find the increased resolution to be at all significant, although it was noticeable at a pixel-peeping level.
The main improvement in the 20D was its vastly improved performance at high ISO, compared with the D60.
