I primary advantage of the crop body is that small moving subjects are larger in the viewfinder; however, I get the idea that the viewfinder will be unchanged and the image file will simply be digitally cropped. Unless I get an improved viewfinder view, I'd just as soon crop the image myself as part of RAW conversion.

I think this feature is mainly for video, where downsizing could be critical to save CF card space.
