That's because the focus points would be too far off center and would not be accurate. Or so I understand from engineers.
Now that I think about it, if Nikon made a dual charger with ports for the old AND the new D4 battery styles in one unit, I think they would sell well. If they would include a charger port for the D800/D600/D7000 battery in those enormous things, that would be even better.
