I don't think this is true all the time. You can get moire/aliasing in any system. You can always construct a scenario in which a frequency is just right to produce aliasing unless your cutoff filter is ideal and filters out all frequencies higher than half the sampling frequency. In fact, one could argue that the tighter the pixel pitch (higher frequency sampling), the less moire/aliasing you might actually get. After all, things like diffraction, as you stated earlier, come into play more at tighter pixel pitch, which act as a natural AA filter. Also, I'm not sure how you use the 14n and M8/M9, but a lot of M users seem to go handheld at very slow shutter speeds a lot of time. Motion blur can act as an efficient AA filter as well.
