All news from the DC Comics Justice League & Green Lantern panel.
* Earth 2 #0 will show us more of the Superman, Batman and Wonder Woman of that earth before their deaths. There will be eight superheroes or "Wonders" of that time. One of them is apparently Terry Sloan, who is now a villain but has some kind of noble motivation for what he does.
