Yeah - I just got back from PAX & PAXDev - exhausting, but awesome, like a non-sport Olympics. The video was certainly representative of a given hour of walking around. SO many cosplayers - perhaps 1 out of 20 people there were cosplayers of some significant effort. I spent a couple lunches just sitting on the floor of the area between the two game-showing areas (the area with the mustache store and the "bromance" pictureboard) just watching folks walk by.
Some were certainly professional - most of the massively multiplayer ones with elf outfits and such certainly had a consistency and coordiation that seemed more marketing than cosplay. But most were just folks, and it was all very cool.
One of the better professional events along these lines was the Dishonored mansion. They rented a large house on Minor Ave., and filled it with dedicated actors to create the "Three masked women" level used in press demos they've shown around. Visitors got paper masks, were served food next to a carved shark, and had strong elements of an "alternate reality game" hinted all over the mansion. Likely expensive marketing - but it was certainly in the cosplayer ethos.
The whole week ended up costing like $2,000 after hotel, food and other costs. But I got to see so much stuff, meet with folks from Ron Gilbert, to the folks from Cheapass Games, I count it as more than worth it after everything, and about a trillion times more valuable to me than a 'I've been to this landmark' kind of vacation.
