Maybe the R3 actually has a 96 Mp Quad Bayer sensor? So far we have seen only results from the pixel-binned 24 Mp mode. The possibility for 96 M photos would really be the mentioned "trick". But well, as it is not practical to have Quad Bayer with an effective AA filter, this is not probable, Moiré would be a huge problem. Maybe the R1 will have that, though, and does some clever tricks to overcome Moiré in the pixel binned lower resolution file. Or even be able to do real time high quality time sampling.
