It was discussed at BOLC last summer and seemed like it would be required... I haven't been able to find any official updates or heard from anyone who applied from the first cohort of NBDE P/F students, but I have just been working on the assumption that it would be.
Guess I fell into the assumption trap though; if its not required for upcoming year I could have used some of this studying time for valuable externships instead. Studying is good prep for attending rounds however, so there's always a silver lining.
That being said, I am trying to track down more information. Best of luck.
