The greater the pixel count, the less the AA filter "gets in the way", so the less "need" there is to get rid of the AA filter. In other words, the AA filter will do its job more effectively with more pixels.

Agreed. Also, with increasing pixels counts (and larger pass-band OLPF), the high-frequency behaviour will probably be less and less interesting.

But the effects of aliasing wraps around to lower frequencies. So in that future 1 gigapixel camera, who would want to risk highly visible artifacts in low spatial frequencies in order to have a little more gain at fs/2??
