I think mostly things concerning Thomas Wayne, but I think we're still owned answers about the whole Gotham siblings deal. I would want that by the start of City of Bane, at least we know more about Bane's cabal and just for how much time all this has been going on (everything seems to be pointing out to issue #1).
My theories are that Skeets' time travel abilities plus Psycho Pirate knowledge of the various continuities is how Bane found out and brought in Thomas Wayne, saving him mere moments before the whole Flashpoint timeline was erased (again). Thomas wants Bruce to stop being Batman, but I'm not yet sure how Bane convinced him to be part of his plan. I wonder if Bane had anything to do with Booster Gold's nervous breakdown (with some help of Skeets and/or Psycho Pirate)---I excuse myself if that is not the correct name of what happened to BG. I'm pretty ignorant about psychology besides some superficial knowledge
Riddler and Joker were convinced after I Am Bane, but Hugo Strange has been with Bane since the beggining. Personally, I like how the original idea of Bane and Strange cooperating so the first could get Psycho Pirate and the second the Venom formula worked, but I don't know if that will be the final version. I guess the limitation of the Gotham siblings' powers was deliberate so they wouldn't become a menace as superheroes with unlimited power. Still, I think more should be going on in that aspect that a Venom derivative. I'm not a fan of Venom being capable of everything after alterning or adding some elements
Great interview. I'm eager to see part 2
