Re: DC's New 52: Reviews and Discussion (Spoilers welcolme and likely)
And the JSA, All Star Squadron and Infinity Inc were from Earth-2. These elements were already integrated as part of the DC Multiverse. The original CoiE was about creating a blank slate since continuity was viewed at the time as a dead weight and it was assumed that a newer and younger readership would emerge after CoiE. On the other hand Nu52 was about more using the reboot to create a sales boost from the same old group of fans with no underlying assumption that there would be any "new fans".
There are three lights.
