It appears that the version of Delirium that I have is now "the old cover", as they have redone it. The new cover is actually very nice, but unfortunately this means that my covers wont match when I buy the sequel :-/ I wish these companies would decide on a cover before they publish, but perhaps that's just too logical. So enjoy the video and the old cover.
Buy: Delirium: The Special Edition, a.k.a. "the new cover"
