@the_stegman: there are multiple spots where the chest logo on Bruce Batman alternates from the yellow emblem and just the black bat.
As someone who doesn't read worlds end or earth 2, I feel a little unprepared for this event. I get that I'm not going to be familiar with all the canon related elements that may be tied in. I feel like these portions of the story may have been better served as a tie-in. I thought for sure the main book would focus primarily on all the crisis elements, maybe slightly referring to some secondary stories but I feel a little lost already. I guess we'll see what happens.
