As has been said numerous times in the thread and probably in the original thread, Batman and Green Lantern were selling for them. Not very much else was. The other thing they decided to keep over into the relaunch continuity is the Legion future. I assume that was probably Paul Levitz's influence combined with Geoff Johns, since Johns brought this version of the Legion back. Everything else was literally up for grabs.
I've never denied the sales success. Or gaining new fans. I have stated that I'm happy for those who have rediscovered comics due to the New 52. I'm glad that people are enjoying the books they are, but we can not deny that there are problems and just plain flaws with some of the changes that DC has implemented. There have been a lot of pros but for me personally I think there are mostly cons.
