IGN's feature today on the various Action Comics #1000-related developments - that issue itself, the hardcover, the return of the suit, Bendis taking the books, today's announced specials for Superman and Action - includes a partial list of creators for 1000, which includes Grant Morrison, Frank Quitely, and Doug Mahnke. Double-checking, I see BC also listed a solicit including creators with that information (to whatever extent you care to trust that). A misunderstanding? Speculation? The article elsewhere erroniously lists #1000 and the celebratory hardcover as both coming out on April 11th; is this a mistake too, or an unheralded exclusive?
