I bet the resolution of the D800, E or not, would dramatically change this situation. Here's a screen grab of the ACR window in 100% view looking at a file including a corrugated screen in glancing afternoon sunlight. I think that the distance/focal-length was such that the corrugation in flat light could have been at the limit of resolution, but adding a shadow from raking light for each "stripe" dropped it below pixel size so [in Carl's original —Ed.] we've got true sensor/subject pixel-level moiré interference:

The patterns on screen change at different magnifications, but they never go away. Based on the 100% view, I don't see how it can go away in a print—the basic structure of the subject has not been imaged, it's replaced by a bunch of false data—but I'll do a test.
The other side of this, however, is that I can easily see how more-than-doubling the sensor resolution could blow right by the problem, though of course the G3 does in fact have an AA filter, however weak.
It does make me wonder what else could set things off—not set off the annoying screen-only stuff, but actual pixel/detail interference, even with 36MP. Rows of windows of buildings on the Manhattan skyline from Hoboken? Cable bridge at just the right/wrong distance? Somebody's Harris tweed jacket in a street scene? Building in background with contrasty brick and mortar pattern?
