Here is an interesting Kodak enginerring article on their new CMOS sensor
technology.

Claimed better noise due to improved CDS, binning in charge domain for reduced
readout noise in
low resolution readout,better for autofocus,better fill factor = better quantum
efficiency,B&W
binning mode for low light level in video applications. Also binning nice for
realtime electronic
displays,reads faster and uses less DSP power. Partially Shared readout
transistor reduces added
sw transistor overhead.
The shared binning makes me think a bit of Foveon's binning for reduced res
readout.
The nice thing about shared binning is it is likely the aliasing remains at the
higher pixel
sampling rate, while noise improves, this is particularly nice for high
performance video.
