On the listing for the Batman & Two-Face 2-Pack on ToysRUs.com, they have the following listed as the description:
Celebrating one of the greatest superheroes of all time, the Legacy 2-Pack action figures takes its inspiration from Batman™ films and the Batman: Arkham City video game. Multiple versions of Batman and legendary villains like The Joker, Catwoman and Ra’s Al Ghul are included. Released in three waves, a total of six 2-packs will be available for fall 2011.
This is an interesting twist. Joker is in both 2-packs of the wave 2 (one from The Dark Knight & one from the Batman: Arkham City video game), so that would allude that Catwoman & Ra’s Al Ghul will be in the 3rd assortment. Most likely, Catwoman from Batman: Arkham City & Ra’s (most likely) from Batman Begins.
PK’s Pulse: This is very exciting, as many of us Batman collector’s have been asking for a Movie Masters version of Ra’s with the likeness of Liam Neeson since the Movie Masters debuted in 2008.
