As far as anime goes and my observations in conventions, Naruto and Bleach are still the biggies while Vocaloid and Hetalia are surely topping them as we speak. I'm sure to see Madoka cosplays become more popular though.

>Hetalia
>Vocaloid
>Touhou
>MLP gijinkas
>Adventure Time is getting quite popular
>Homestuck
>Homestuck
>Homestuck

And Naruto and Bleach seem to be keeping popular.

This

New big ones seem to be Tiger & Bunny and Ao No Exorcist

Also another oldish one is Panty and Stocking

>>5272908

Madoka is already really popular

>>5272911
Whoops, forgot Madoka
also Pokemon gijinkas
and Black Rock Shooter, we'll probably see a fudgeton more when the anime starts airing.

Hush, you. /a/nons don't get out of the house or attempt to interact with 3DPD more than is necessary. His last convention was probably last year or so.

>Vocaloid
>Bleach
>Homestuck
>MLP:FIM
>Kuroshitsuji
>Panty & Stocking (on its way out I think)
>Madoka
>Hetalia

I think Sailor Moon will become popular in 2012 because of the re-release of the manga.

woah woah woah, woah. BRS Anime? I knew there was a game but I didn't know it was becoming an anime! I really liked the OST so I won't lie, I would love an anime.

Persona 4

*thumbs up*

Last con was August of this year.
>inb4 it was probably a sucky and/or small con

>>5272952
Yep! It comes out in a month or so. I really like Huke's character design (and of course anything Supercell related) so I'm very excited although I was a little disappointed by the OVA.

>>5272969
Really! Oh gosh can't wait! Thanks for posting that! I really liked it but the story line was a little odd, and how they kept jumping back and forth didn't really help I think. I hope in the anime they just focus on the BRS world. Do you know if any of the game characters (WRS/Strenght) will be in it? Also if its becoming an anime I agree that it's just going to explode all over the cosplay scene.

>>5272956

Well, it wasn't Anime Expo or Otakon, that's for sure.

>>5272976

Just look it up.

The designs have been revamped a bit, Deadmaster looks a bit different.

>>5272976
Strength'll be in it, as well as Black Gold Saw. I think they'll keep doing the human-blackrockself (sorry..don't know how to describe LOL) thing though.
Here's the wiki page if you're interested: http://blackrockshooter.wikia.com/wiki/Black%E2%98%85Rock_Shooter_%28anime_series%29

So far here are the following:
1. Homestuck is the big series to cosplay from. Especially the character Dave.
2. MLP cosplay.
3. Vocaloids are still going to be big.
4. Madoka
5. Pokemon Gijinka is going to be big as well.

>>5272911
Basically this, but I'm going to add Tiger and bunny, Persona 4, and Sailor Moon
