Updates on io9 from an interview with Dan DiDio:
Paul Levitz is synonymous with the Legion of Superheroes, but DC's published many different iterations of the Legion. Can you give us some hints about what Paul has planned?
DD: The good news on this is that we've had a lot of positive reactions to what's going on with Paul on Legion of Superheroes, and he's got a very distinctive style that is really something that plays to long-time Legion fans. I'm happy to say we're going to be continuing with a lot of the direction and tone he's set currently on the run. That's probably one of the books you'll see the least amount of change taking place, other than the subtraction of the characters in Legion Lost.
Let's talk Legion Lost — is there connection to Dan Abnett and Andy Lanning's miniseries of the same name from a few years back?
DD: The [new book's] title is Legion Lost, but that's where the similarities end with the Legion Lost that came before. What you're going to find out is that this Legion is lost in present time with no way to get back to the future — this is a team of Legionnaires who are trapped on Earth with a very specific mission to accomplish. They're not sure how to do it given the parameters of how the world exists right now.
