So it appears there are still advances to be made, improvements yet to
come...

Ok, it's only a 5Mp sensor at this point, but if this design (which makes
me think, why haven't they done this before? (or have they? - this isn't
really my field)...) can be produced relatively cheaply and for higher
res sensors as well, it will put some good competitive pressure back into
the market.


I didn't see where it was cheap but that'd be great. I would get a Nikon
D30 Fx format even at 4MP if it was cheap & small.

"Conventionally, consumer digital video camcorders and digital still
cameras have been required to combine high resolution capable of capturing
every detail of the subject matter, and miniaturization oriented to
portability. In order to meet these needs, image sensor development has
focused on miniaturizing pixel size, while maintaining imaging
characteristics. However, in addition to these ongoing requirements, in
recent years demand for improved levels of minimum subject illuminance and
rapid image capture has also increased. This has led to the requirement of
image sensors with improved signal-to-noise ratio and other features
capable of realizing improved overall picture quality."

It seems I've heard of back illuminated in astro & scientific work...

Yes, but have you heard of the F frame cat sensor? It can be found in any
adult cat, and because it has a tapetus lucidum has excellent night vision
(low light), also very good MP rating in bright light, the problem is
meowing which can distract from picture taking.
