Interesting. Though, curious question. Mind you I don't cosplay(not exactly, I dress as a ninja), but is this just being announced now? I ask because it seems like this might've been better announced awhile ago if it hasn't because some people may have done different costumes to try and compete in this category. But now, two days away, it's kinda short notice.
No offense I mean, just a curious observation. I mean I know people dress as various characters and I still see cosplayers of older series around so it's not like there wont be anyone to actually compete for this I'm sure.
