I apologize if this has been discussed before (if so, could you please let me know which thread) but is it known which stories from the pre-Flashpoint world still apply in the DCnU? I was reading GL and it was talking about Blackest Night. Also, Nightwing goes into Dick Grayson's past so you know that he has had the same childhood and all the other Bat family members have their pasts as well. If it is not known, do you think that it is frustrating that you have to guess what actually has occurred in the past?
