Can a lens like 18-200 VR (brought out with D200) resolve more than today's 16 megapixel sensor?
Are discussions like "this lens vs. this lens?" a moot point then?

It is not like that.
You have to look at it a different way, really. One source of softness is the resolving power of the optics. Another source of softness is the sampling rate of the sensor. Those get added up.
So, while a 180mm f2.8 may give sharper results than that 18-200mm on a 12mp sensor, still the 18-200mm in combination with a 16mp sensor can resolve more than that 18-200 with a 12mp sensor.
You add up all causes of softness.
