From his weekly column at Newsarama:
7. One question that came up a few times in the thread – what happened with Legion of Super-Heroes #50?
DD: It’s pretty clear, and I answered this at one of my panels at the con, but I’m more than happy to address it again. What happened was that upon the author’s request, there was a name change and a pseudonym used and we obliged that request. We made those changes at the very last minute because we did not want to miss our shipping date on the book. We made a couple of changes in order to get the book out on time, and we felt that it summed up the story to the best of its ability, and we’re ready to move on to the next chapter of Legion wherever that may be, following the conclusion of the series.
12. Moving on to a question about something you said about DC having an increased commitment to the Legion of Super-Heroes in 2009. Last year at this time, there were two series, and an animated series. This year, the regular book has been cancelled, and they’re going to be doing what looks to be a time-share thing in Adventure Comics. What’s the increased commitment going to consist of, coming up?
DD: Well, we also have Legion of 3 Worlds coming to a conclusion too, which is a very important book for the Legion franchise. But the commitment is that we’re bringing a level of clarity to the Legion and one direction that shows the potential for the future of the Legion, but also how that future is springing from the current storylines in the current continuity.
So what you’re going to see is how the Legion has ties to our current timeline, and once we establish those ties to the current time, we’ll spring forward to the future an d see what the future holds for those characters.
NRAMA: So mostly, we’re going to see more of firmly-established clear-line continuity than it’s had previously?
DD: Right. One of the things that I found most interesting about Legion of 3 Worlds was that the delineation between the three Legion teams were slighter than we had originally thought. They were variations of each other rather than different focus, different plans between them. What we’re trying to do right now is to bring a level of clarity to everything, the Legion included. Following Blackest Night, we’re looking at a much clearer, iconic interpretation and a much more committed determination to the direction of our characters. Legion is no exception, and we wanted to clear the decks a bit, straighten things up and get things rolling again.
