To my knowledge, Swallowing the Earth and Barbara are both out of print and it might be a long time before DMP reprints them, since right now they want to focus on releasing untranslated Tezuka. I think Unico was bought up quickly because it's a popular title in full-color--manga is rarely ever published in full-color, so it's a collectible because of that alone.
