I think the price is justifiable given the extra picture and sound quality offered by HD. You can't have cheap *and* high quality. If you want better quality you have to pay for it, if you can't afford it you have to make do with lower quality or earn more money. That's aspiration - the drive to work harder / more to be able to afford better things. But I digress.
However, releasing one volume of a series with no guarantee the rest will ever see the light of day... And doing it not once but three times is beyond a joke. It's farcical. I don't dislike Manga. They have given us a lot over the years and ironed out a lot of problems, but this is just destroying any faith BD buyers have in them. For us this is ADV and Revelation's partial release fiascos all over again.
