I half remember reading that Nikon full-frame cameras do something similar if a lens designed for their APS-c cameras is attached. Given the likely cost-per-unit advantage of APS-c sensors, it may not be a bad idea. Some of the extra pixels at top/bottom and/or the sides could be used for other things, maybe even as a dedicated focus aid etc. etc.

You're right that they certainly could use a full APS-C sensor, and just crop for the imaging pipeline. It would require a certain amount of extra work (and waste some space in the bodies) but it's by no means impossible.
However, the 16MP sensor cropped to 4/3 size leaves about 10MP which is probably not enough. Even the 24MP sensor when cropped only gives 16MP. And the 24MP sensor doesn't seem to be any better, on a per pixel basis, than the current Panasonic 16MP sensor.
Regarding the costs, Sony has the volume advantage, but Panasonic has the size advantage (larger size invariably makes for lower yield), so I'm not really sure who comes out on top in the end. I wouldn't be surprised if it were a wash...
