In the future, when the resolution gets even higher, we will see true sRaw implementations.
With a 50MP camera, you can take a matrix of 4x4 sensels, and true pixel bin down to a matrix of 4 sensels. That gives a 12MP sRaw file without having do de-mosaic, downsample and re-mosaic.
Now, how about the AA-filter then? It can be implemented digitally too. Just include a few sensels surrounding the 4x4, weighted down a little. Actually, I strongly believe that\'s how Canon is going to solve the jagging problem in video with the coming Digic V processor.
Great plan, and I wonder how much light the colour and AA filters stop. The problem of course is that the camera will be marketed as a 50 Mpixel camera. In those terms it will suffer from moire, and it will also require spectacular lenses. But as you say, if the goal is a 12 Mpixel file, it could be superb.
