If the newer models have been set up for mid grey - that I do not know. I will enquire of some cam shops for currrent info. At the time the digis came out, I thought, why did the calibration change?

Norm,
I am slightly confused reading this, but then my brain is slightly out of gear from research for a previous thread.
Two separate things appear to be involved here. White Balance which affects colours, and Exposure which ranges from white to black tones.
As Duncan says light meters are calibrated for 18% grey and always have been. So provided the WB is accurate, and metering is taken from an 18% grey card the white card will appear white. However if the WB is off, but the exposure is accurate, then the white card would have a colour cast.
