Here is an interesting analysis about the sales of the New 52 centering around November...
From that analysyis:
One of the two notable things the “New 52″ hasn’t done, though, is to flush new audiences into the direct market — or if it has, it hasn’t been in the kind of quantity required to grow noticeably beyond the pre-existing comics audience. DC gave it their best shot, but the ceiling of the market, in terms of units, is still broadly the same as it was five years ago, when the big DC Comics publishing events of the year were called 52 and “One Year Later.” Given the unprecedented promotional push, large-scale returnability incentives and lip service paid to the idea of attracting new readers this time around, this failure to expand beyond the existing direct-market readership is well worth mentioning.
The other thing the “New 52″ push lacks, to date, is the kind of sustainability needed to extend beyond the initial 52 relaunch titles.
Yeah, I figured this would happen. Beyond a few cosmetic changes, there was nothing there to bring in new readers (ie, kids or women).
