Wonder Woman isn't getting a collection soon due to its alternating storyline format. Detective Comics, Action Comics, and Hal Jordan and the Green Lantern Corps will probably be out in February. Also looks like they'll be $16.99 all across the board, regardless of page count. And going by Nightwing, DC is keeping crossover issues separate in their own trade.
