EOS Bodies / More colors

Todays sensors have heaps of megapixels.  More than you can shake a stick at.  More than most of us need.

Now, today's sensors still have a bayer filter with a basic R,G,B pattern.  RGB is what our monitors use.  Newer sensors have standard green alternating with an expanded green, but it's still pretty much the same idea.

What if you created a color filter that sampled the color spectrum in a different way?  You could sample a wider spectrum for richer violets and deeper reds.  These two colors are weak on DSLRs, something I miss after switching from slide films like Velvia.

You could also sample the spectrum more finely.  Either way you'd end up with a wider gamut.  Maybe a computer monitor wouldn't show the full extent of the improvement, but a good quality print should.

So, the idea is to use these sensels to record more color information, rather than focusing in spatial information.

In the same vein, some sensels could have a darker filter on top (e.g. RGgB where the g is 3 stops less sensitive than G) for wider dynamic range.

Third Party Manufacturers / Any rumors about Adobe CS6?

Anyone have an idea when Adobe is going to launch CS6?

I was about to spring for a CS5.5 suite but my store was out, and said they probably wouldn't get any more copies until the release of the next version.  The sales rep was guessing later this month, then shipping a month after that.
