I am an applicant to UMass this cycle that interviewed last cycle in October and was played on AC. Obviously things change, but last year most people who were placed on AC including myself got an answer back very close to the end of the cycle in April, where we either received our As, Rs, or in my case WL.
All that's to say I'm back at it again this year applying to my dream school, still holding out hope for another II as I remember there was still a little bit of action around this time last year.
