Waid wasn't the point of my post. My point is that, apparently, Berganza learned a big lesson: good stories are more important than continuity. If Birthright is a good story but it fucks with continuity, so be it. The same goes for the other books: they will be so different from each other that they will contradict themselves (for example, on the way they show Lois, like DiDio said on Newsarama). I was kinda thrown off by Austen's decition of showing Lois as a bitch, but now I don't give a fuck, because it doesn't mean she has to be a bitch on the other books.
And, yes, three Superman books will be linked... but they will be LEX LUTHOR, VIGILANTE and THE QUESTION.
