Well, I was kind of ranting I admit and I certainly hope DC does this right but I don't really see how it can be done right with 1500 pages in one volume, no matter how thin the paper is.
Even a slip-cased two volume set would still probably be too unwieldy.
Invisibles breaks down into 3 books so it makes sense to divide them that way, even if volume 3 would be significantly thinner than the other two.
Anyway, as much as I want this made availabe, especially for people who haven't read it, I won't be holding my breath. Vertigo has proved they can do it right with the wonderful Fables and 100 Bullets so why eff with success?
