Looks like the hint wasn't an AF joke. Later in the initial tweet he would comment Players gonna play, play, play.
Taylor Swift has been guessed and she was where I went as well. Someone mentioned her album 1989 and that would tie in with 1984 last year, but just like how 1984 last year referred to Sam the Olympic mascot I think 1989 is a hint at the code name and not the actual code name.
EDIT: Since this is the maze that is going to be announced at Monsterpalooza is it safe to assume it is a Hollywood exclusive?
