I can guarantee you that there are more than 40 people on UF's waitlist. The school interviews over 300 for 80 spots or so. Most people accepted to UF go because it is the state's only "state school" --> CHEAP.
It seems as if the school puts people on their waitlist that they know they will never get to. Sad, but true.
A buddy of mine in the c/o 2010 got pulled off it very late. I was put on it and never heard a thing. Best of luck to you.
I recently interviewed and we ask Dr. Sposetti specifically on this. She said last year I believe that there was only one person pulled of the waitlist. Supposibly the guy got in, fell in love and moved to another state to follow the girl. She says it can happen but it's really rare people whom are accepted to UF would give up their spot. You have to realize that 70+ are florida residents and a lot of them are from UF so they will likely choose UF if they have a double acceptance.
