So I just decided to call them for an answer, and they said that the application will open sometime in May. I asked when the application will close, and he said he doesn't know because he doesn't know the exact date that it will open. I think, traditionally, it remains open for two months, but I'm not sure.
I also asked him if they often change the application essays (I wanted to get a head start on them), and he stated that they often do so to not to bother writing essays that answer last year's application questions.
