I stand corrected, Brian. I was confusing Meter with Sensor. That said, I stand by my position,...how much better meter do we need? For that matter, from November through March (about half the year), I shoot mostly basketball,...in Centerweighted. So, I'm sure the meter in the D7100 (and the D7000 for that matter) is all I will ever need.
Thanks, for the info, though. I didn't realize the D90 and D300 had different meters.
