Dunno if this is in or out continuity. By the looks of it, I'd say it's one of those stories that are in continuity, but happened in an unspecified time in the past. It's there, it happened, but it doesn't affect the current stories at all.
Is this book relevant to Magog's role in Generation Lost? I don't really understand why DC decided to release this as a special instead of two more numbers in the Magog series. I'll pick this up, because I love Scott Kolins art, but I don't expect much from it...
Seriously, this is a collection designed by Zazzle, not DC, and not every character is featured in every item. You're making it look like DC completely forgot about Wonder Woman, when in truth she's featured in more items than Flash, or any other character who's not in that badge for that matter.
Awesome cover. I'm digging the new suit... but those gloves. The humanity! Why are they padded? It looks more like suitable for an exoskeleton than for a Batsuit. Also, the years a bit short, if you ask me, but that's just me :P
