There's other strategies that can be done like gradient direction detection, etc. depending how far it's taken. Several Bayer cameras are doing some stunts on that end also. I see the benefit for the Quattro in still having more color data.

Yes, that is heavily done in Bayer reconstruction.

Its a two edged sword though.

It is the main reason why Bayer images can be so sharp, but also the main reason why Bayer images have so uneven sharpness over the image. The latter is a big disadvantage and thr former a big advantage.

You alos have to understand that the gradient detection algorithms may create edges that are not really there, i.e. creating sharpness where none is found. This might be one of the reasons for the lack of 3D look - the DOF does not work reliable. Sharp things are soft and soft things are sharp.
