So it seems that this new wonderful sensor only performs AS well as
previous 12MP sensors...it's just learned a few new tricks. Current
cameras don't bin, so this could be an advantage in terms of feature
set. But I think it questionable as to how advantageous binning is
to the kind of photography we generally discuss. This may matter to
celestial photographers...don't know how much it will matter to
others.

The way I see it, hardware binning is of limited value. It can reduce read noise, but I appreciate the finer grain of the full capture, despite higher noise. I'd have to have very high oversampling before I'd appreciate it, I think.

Statistically, of course, hardware 2-> 1 binning can reduce image-level read noise by up to 29%. That assumes 2 pixels with the same sensitivity; I'm not clear on whether Fuji does this.
