This is how it looks like up front and not even inside the exhibit hall.
For some people who don't know, some people don't even buy a badge to go inside. They just dress up in their costumes or what you call a "cosplayer" - a person who dresses up like a character from a manga or anime series, a movie, a videogame, etc. (from Urban Dictionary). They just pretty much hang out there and pose in front of cameras.
(I think this year's AX broke the record of last year's attendees.)
