Yaoi-Con 2008 | A Celebration of Male Beauty & Passion in Anime & Manga

Assuming there is a book 12, of course. There never was one in Japanese, just a couple of serialized chapters afterwards, because Matsushita had to go on a long hiatus for personal reasons. But I hear she's been working on it again recently, has put out a story about Tatsumi and one about Ukyo (haven't seen the latter), and her art style has really changed, though I wouldn't say unpleasantly. Maybe those side stories were what the Viz people meant.

Here's hoping she'll at least finish the Gensoukai arc, though. A couple months, I would be surprised, but if that's true it's awesome.
