You can do that right now with the D800. Image size settings are adjustable just as they are in all other Nikon DSLR models. No doubt that for some shooting a lot of people will be shooting at one of the medium settings in the D800 (e.g., 15mp - which is essentially the same as the D7000 but full-frame/FX of course).
