Over at Newsarama, one of their writers talked about how many of the story seeds dropped by Scott Snyder at the end of his run of events at stories over at DC Comics didn't all pan out as expected. All of this is completely speculative on my part, as I have no idea where things are going to land.
This is what happens when 1) publishers rely too much on a treadmill of events to sustain interest, and 2) the architects of the big events don't stick around to sprout the seeds lain by their events. As Scott Snyder lead the DCU through Dark Nights, the No Justice Era and then into Death Metal, successive stories picked up what was being laid down because the writing architect was there threading the needle through the events and story arc. Then with Death Metal, Snyder laid out the after effects of his massive run...and then went off to do creator-owned books.
