I think a lot of us have already came to this conclusion before but when you hear things like this from creators working for DC it becomes all to clear that DC had no solid plan or blueprint set up before they started the reboot. From now on whenever something comes up that they need to change then they'll just change it with no explanation and they won't care how contradictory it will make things from previous issues seem.
Lobdell on Teen Titans #0: "Teen Titans #0 is almost exclusively about Tim Drake. We keep most of the origin in tact," he says, though stating that as far as he can tell Tim Drake went straight to being Red Robin and had no official time as Robin, "in that he was one of the few people to get really close to tracking down who Bruce is. It'll feel like The New 52. It'll be a new, updated version of the origin. I'm really excited about it. No less a person than Scott Snyder said it was awesome."
If Red Robin just started the Teen Titans, how is the flashback with Nightwing explained? "It doesn't show the Teen Titans, it shows people who used to be on Teen Titans hanging out together. There was no reference to Teen Titans. My feeling is that in the DC New 52, yes, these characters have crossed paths before, but there was no previous version of the Teen Titans. That group you saw in flashback was there, but they were not 'Teen Titans.'" Lobdell says that originally there was going to be more history with the Teen Titans, but plans changed along the way, and might change again.
Fan: "Doesn't Red Robin say 'this will be the shortest-lived incarnation of Teen Titans ever?'" Lobdell: "Yes, he did say that. That was written at a time when there was going to be [other] versions of the Teen Titans in the Teen Titans history. As it is now, in this continuity what he was referring to was this comic book he read as a kid called 'Teen Titans'... give the man a prize, will you?"
All of this just makes me hate the reboot even more.
