In another couple of years, no camera worth owning will have an AA filter, so I suggest the aliasing police get used to processing the output correctly, and enjoying the superior microcontrast and detail easily available.

You cannot fix the aliasing caused by insufficient sampling combined with no optical low-pass filter.  You either have to have a filter or you have to have sufficient pixel density for diffraction to act as the filter at all f-stops.  That's a lot of pixels (hundreds of megapixels to gigapixels depending on sensor size and f-stop required).
