Titan Merchandise and Matt JOnes (Lunartik) & myself) have announced two more series of TITANS mini figures. The Buffy the Vampire Slayer TITANS includes the 12 figures shown above in blind boxes. They are slated to be released in January 2015.
Also, the Dragon Age TITANS (apparently from a video game I"m not caught up on) are slated to begin hitting retailers around December 2014. As with other releases, Lunartik will have several artist proofs available via his site around release time.
