Just a heads up that the web site for the Production I.G. film 'Musashi: The Dream of the Last Samurai' is active and contains an interview with the director Mizuho Nishikubo, a look at promotional material available with advance ticket purchases including katana hilts and wall scrolls, and other goodies. Sadly it is all in Japanese and I don't know a lick of it and I am not about to trust Google Translate with the interview. For those of you with more prowess with the Japanese language I will direct you here.
It's an animated documentary of Miyamoto Musashi.
YES I need more Oshii after Sky Crawlers, yum!
Though I don´t think this could surpass my dearest Inagaki trilogy.
The best info on the film I've found so far in English is on the Production IG website:

I'm intrigued by mention of an onscreen "3DCG generated Musashi expert."
