Supposedly, if this works, it should make the Sony even more capable
than the Fuji S3
at handling scenes of widly different levels of illumination.

If I know, the Sony's 'bizon' processor writes RAW at first, than does
some image manipulation on image levels. Fuji f3 has phisical exttended
range, because of specyfic sensor.

I wasn't sure whether it worked during image capture or not.

The Fuji S2 and S3 use additional lower sensitivity pixels to extend
the highlights (by about 2 stops). There is no way that you can
substitute for a physical measurement and achieve honest detail without
adding artifacts (such as quantization noise). These artifacts in turn
are probably "smoothed" in some way, so then the fidelity is lessened
yet again. Whatever it does, it's better than a burned out white area
in most cases....
