The Australian Ratings Board is known for accidentally letting games slip prior to their official announcements. Today's most recent leak involves Konami working on a collection of Game Boy Advance games for new platforms. Simply titled Castlevania Advance Collection, the game is listed as having M2 working on it as a developer, who previously assisted in re-releasing the highly-acclaimed 3D Classics line of SEGA games for the Nintendo 3DS. If the re-pack is legitimate, which it almost certainly is at this state of being rated for official release, it would likely feature the three Castlevania games that were available for the GBA: Castlevania: Circle of the Moon, Castlevania: Aria of Sorrow, and Castlevania: Harmony of Dissonance. No further details such as platforms or release date are currently known.
