From Greg Rucka's interview in Newsarama (I read it for the tiny chance that he might say "Oh, yeah, and the guy's writing the other Super-book is Morrison"):

Quote:

“In [January’s] #636, Superman, Batman, and Wonder Woman have their first big meeting since the events of Identity Crisis,” Rucka said. “Those who are not up to speed on what happened during Identity Crisis, meaning the characters who weren’t aware of all the sordid secrets, find them out. It leads to what will be the start of a huge fracture between the three pillars of the DCU. You’re going to see the beginnings of a breakdown.
