JN, didn't CG refer to the place holder thing when he was talking about their first presentation at AAN 2012? At the 2012 PPMD webinar he said "We had a late breaker abstract accepted at the AAN that is to take place in New Oreleans from April 21st through the 28th. The lead author on the abstract was Jerry Mendell, our principal investigator of our phase 2b study, and it was accepted as part of their emerging science session, which was formally called late breaking science."
Mendell also had a late breaker slot for his presentation at the 2012 WMS presentation of 48 week data where CG said there would be more detailed info. Is that what you were thinking about?
I am guessing that you believe Sarepta also has an abstract accepted for the late breaking session? This year it is again on the last day, Oct 3rd between 2:30 and 4:30 pm.
