If Emory hasn't changed in the 30 years since I was a grad student there they'll piddle around with their investigation, hoping the furor will die down, until either 1) it actually does die away and they can quietly close up shop w/no decision or 2)the book is finally accepted by the bulk of other historians as the POS it is, in which case they will issue a mildly worded report and hope no one notices.
BTW, I finally left Emory after two almost totally wasted years, and went down the road to Georgia State where I got a decent, non polticised, education.
As someone I know once said to me; "They may call Emory the Harvard of the South, but they sure as hell will never refer to Harvard as the Emory of the North".
Come to think of it tho, they are the same in one area; left wing political correctnes.
