I'm getting to the point of frustration with these people. If they can't afford to be in both businesses, they ought to shop for a buyer to take over their manga rights.
It seems to me that outfits like Seven Seas and Yen Press continuing to license and produce new titles with no sister Anime business at all prove it is quite possible to do business as a Manga provider. Maybe ADV should sell their manga licensing to of these firms instead of sitting on them and letting interest in them go cold.
(That sounded a lot more grown up than crabbing "I want my Yotsuba NOW!" didn't it?)
