Hey everyone,
I'm not sure how new this information is, or even how official it is, but it could be something. According to
THIS BLOG ENTRY, the new Burimyu set for July-August 2011, will be based on the anime-only Bleach arc from last year; the Zanpakutou arc. I received the link from Nacchan on the Bleach Asylum forums, so I'm not sure who that blog actually belongs to.
(For anyone unfamiliar with that arc; As you all know, Shinigami carry swords known as zanpakutou, within each zanpakuto resides a spirit. This anime-only arc was based on these spirits materialising into somewhat human forms (some looked a little less human than others).
I'm not sure how legitimate this is, but I thought I'd put it out there to see if anyone can confirm this information, or tell us otherwise.
