And that's for regular releases. I'd be surprised if the initial drop wasn't much stronger for something that has already been a living legend for many years. That initial wave of "oh, I've heard so much of them, probably won't play even with a graphical mode, but I still want it in my library" is one of a kind. The long tail will probably be much flatter, but only compare to regular releases once you separate out everybody who bought in roughly the same way those nice hardback Shakespeare collections are bought.
