The new syllabus has them doing around 14ish low levels in advanced. Inevitably they get weathered out and it is taking months to get classes off the flight line. I was there for the transition from the old to the new syllabus and it was a mess. Makes sense for them to slip some class dates for breathing room.
I believe 13-15 was administratively cancelled and renamed 14-01. I know they shifted a couple classes to address some training issues. So I don't think you are going to see anything.
