Batman:Legacy Edition is a line dedicated solely to Batman and related characters and properties, stemming from DC Superheroes and DC Universe Classics.
The main line of figures are essentially redecos, kitbashes or figures with minor retools - a welcome move to produce more variants of the Batman franchise in a separate line from DC Universe Classics. Unlike the main Legacy Edition however, the Arkham City figures feature mostly new tooling.
The line was revealed just a few days before New York Toy Fair 2011 online by a poster who released photos of digicustomized previous figures as well as images of custom repaints that have been done by customizers, stating that the figures belonged to the first two waves. Of course the 'leak' was met with disbelief but all the figures that were presented were eventually officially announced. The line was shipped with the new game-based toyline, Batman:Arkham City, as well as a continuation of The Dark Knight (Movie Masters) toyline, now marketed as Batman:Batman Begins. Both series are solicited under the banner 'Legacy Edition' but the packages retain their respective series names.
