The "measured ISO" of the GH3: Surprise, surprise

I think everyone (me included) expected this difference between the two manufacturers to stay the same with the introduction of the GH3 so that ISO 200 would in this case correspond to a "measured ISO" of approximately 200. As far as I can tell, however, such is not the case. On the contrary, the "measured ISOs" of the GH3 appear to be just as far below the camera ISOs as on the E-M5.
