Perhaps you could focus on the cameras that are shooting with 2/3 inch CCD sensors with 2 Mpixel resolution and determine the relative MTF of 1920 x 1080 versus 1280 x 720, as produced by the same camera with the same lens.
The same camera with the same lens will have the same MTF, whether it is putting out 1920 x 1080 or 1280 x 720. It will have more contrast at 1280 than at 1920, but that contrast should be the same whether the camera is in 720 mode or 1080 mode (not counting some minor losses in scaling).
