Can someone explain to me why they're working on this rather than more megapixels? Rather, why the focus is on more layers? I understand it's to better represent colors. But what is wrong with colors? My cameras have always nice, realistic, vivid colors as long as I use a good lens. I've never had a photograph where I even had the slightest hint of a thought that the color is not accurate. When I look at my pictures, it looks like when I was there. Granted, the dynamic range is not the same, but we're not taking pictures with our eyes, so that's expected. What is it about color that they need to squeeze that last 0.01% of color accuracy out of the camera?
The problem with Bayer cameras isn't color, it's that the Bayer dyes absorb something like half the light coming in. In theory, if you could go without that dye layer, you could gain a stop, or perhaps a bit more, of high ISO performance.
