I think it takes a minimum of 2 pixels to define a line's edge.
However, the anti-aliasing filter restricts ultimate resolution
to maybe four or five pixels in actual practice. I have yet to
see any image on DPREVIEW from any camera that had a sharp
one-pixel edge. Please point me to one if you know of it.
Theoretical and practical are two different things.

Possibly true. However in actual usage, I'm finding that my
lowly 100/2.8 outperforms the 14-54. In a couple of shots I've
hit what appears to be the limit with the AA filter!

Think of the higher MP sensors as a finer-grained film. More
pixels doesn't necessarily improve resolution, but it will
improve the transitions.
