The new books are:
--Talon by Scott Snyder, James Tynion IV, and Guillem March.
--Sword of Sorcery, an anthology S&S title. The lead feature will me Amythest, Princess of Gemworld by Written by Christy Marx and Aaron Lopresti. The initial backup will be Beowulf (Oh HELL YES!) by Tony Bedard and Jesus Saiz.
--The Phantom Stranger by Dan DiDio and Brent Anderson.
--Team 7 by Justin Jordan wand Jesus Merino. This is set in the early days of the universe and features Amanda Waller, Dinah Lance (Black Canary), Steve Trevor, John Lynch, Alex Fairchild, Cole Cash (Grifter), and Slade Wilson (Deathstroke).
(Aside: I LOVE the 1970s DC Beowulf book. One of the most insane comics I have ever read. So glad to see him back!)
The only announced cancellation so far is Justice League International. 3 more titles will be cancelled to keep the ongoings at 52.
Zero Month takes place in September and serves as the launching point for the new books as well as a stand alone, origin/backstory tale for the other books.
