Correct me if I am wrong: I guess, increasing sampling rate would still result in aliasing, albeit for a repetitive pattern with a higher spacial freq. Because, real world patterns have an infinite bandwidth.
The number of times a repetitive pattern causes trouble is generally low and it would only be for very high spatial frequency regions ie regions of repeating pattern of very fine detail. So increasing resolution will move the problem to a region of different spatial repetition frequency. Hopefully these regions will become less and less a problem as resolution increases. So they'll probably keep an AA filter for a time to come, but it will most likely , but they should become weaker as MP counts increase.
I should note that of course this is for stills. The problem of course is that video is relatively low res (1920x1080 max and not increasing for a long time) and optimising the AA filter for high res stills, may actually be worse for video. But that's another topic for discussion.
