Truth is, we just don't know until anyone from the industry cares to fill us in on the details. We've had hints from Andrew about Beez having a BD 'schedule' for a long time but nothing concrete yet - I don't know if Expo is likely to yield any results or not.
I would still have thought there was a more viable market for anime on BD than there is a lot of things, what with the Playstation gamer / anime connections - The two often go together. That's not to say that everyone who owns a PS3 likes anime, but a lot of people who like anime own a PS3. The general feeling I get from people on the 'net is that a lot of them (me included) are waiting with baited breath for BD to take off. It already is doing in the US to some extent, but that's mainly region locked Funi titles.
