MP's are an easy marketing tool, so pocket point & shoot cameras with tiny sensors were packed with 16mp years ago.
As to the lens aspect, yes, a more densely packed, properly executed sensor will reveal poor technique and lenses when images are viewed at 100%. However, Nikon is not the only manufacturer of tack sharp lenses. The resolution on my Tamron 17-50; Sigma 8-16; Sigma 150 macro, is phenomenal... The new Sigma 50-150/2.8 is said to be one of the sharpest zooms some reviewers have ever tested.
