I expect the CME to lower margins again as they have been losing too much volume and profit in the various trading pits since the huge loss of confidence due to MF Global fiasco. BTW, they may never get this confidence back or at least take years. In my view confidence in markets and government data and those who regulate them has never been lower or present more risk than at present time. And more regulations will make it worse as what is needed is enforcement of exisitng regulations and more/some jail time for a few Wall Street type bankers plus a whole new congress and President.
