Using the multi-aspect sensor from the GH2, but omitting the multi-aspect feature just seems strange to me. If the sensor supports it, why not include this feature, which one that I've appreciated...

I don't believe that the G5 and GH2 have the same sensor. The GH2's sensor hasthe "variable aspect ratio" feature that was also present on the GH1, and the G5 does not.

Actually, it suggests a 1" sensor, since that's the same kit lens focal range as the Nikon 1 cameras have.

Another sign that it's related to the Nikon 1 is that the kit lens shown in the promo piece is 10-30 mm. That suggests that at the very least it is the same size sensor as Nikon 1. If so,...

From the quoted specs for image resolution in the different aspect ratios, it appears not to be.

Judging by the resolution specs, I'd say the answer is no. I note that the pixel counts for the 16:9 and 4:3 aspect ratios both fit inside the pixel count of the sensor in it's native 3:2 aspect...
