Kinda disappointed that there isn't one on the list! ): there was a huge turnout last year, and this year I actually have a Ryuko cosplay ready.
There's still time to make an official one but if that doesn't get done, I would love to find some people to meet up with for an unofficial one! I for sure have a friend going as Mako and possibly Mikisugi.
I have Satsuki, but the only possible day I can do this would be Day 4. :(
I was hoping for a KLK gathering too. :[ I'm making an armored Senketsu suit that I'll be wearing in saturday.
I haven't had the time to take a complete shot of the full suit, but here's a WIP (https://scontent-lax3-1.xx.fbcdn.net/t31.0-8/12747440_1690052634614013_2996650524855145655_o.jpg) from a while back. Not sure if I wanna call this a "Genderbend Ryuko" or just simply "Senketsu". I'm sorta leaning towards "Dark Knight Senketsu". (been playing a lot of FF14 :P)
As of right now I am planning on cosplaying Ryuko on Sunday ):
