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.
