Well, Gedo Senki seems to have been a bust, but here comes a new literary adaptation to anime that I can start obsessing over instead: Les MisÃ©rables. The official site already has a trailer up. This one is going to be a series, rumors are about 52 episodes.
What made LesMis great was the underlying moral about how doing the right thing, no matter the cost, paid off. I think that in series form, LesMis will translate far better, because any adaptation faithful to the source MUST have room to explore the running themes of redemption and self-sacrifice.
UPDATE: Don says that Romeo and Juliet are also fair game.
