Quite true but for those of us amateurs I think we might see more variation in output from those who can dedicate the time for processing (and have financial incentive) and those who can't.
The D800 is tempting for me but honestly I'd probably go with a D4. It will be a little more forgiving and still have great performance, maybe even better performance minus resolution. Of course, I doubt the D4 will actually improve my photography by all that much! Which is why I don't know if I will get one or not.
