When games get close to release, they can occasionally get accidentally leaked through the various video game rating boards across the world. In the case of the unannounced Castlevania Advance Collection, its existence was revealed back in June, when the Australian Ratings Board let it slip. Konami still hasn't said anything official about the collection existing, but it has been leaked a second time, through the Taiwanese Ratings Board, which has given us new information in the form of the platforms Castlevania Advance Collection will be coming to. It'll pack together the three Game Boy Advance Castlevania titles, Aria of Sorrow, Harmony of Dissonance, and Circle of the Moon, and will be available on PlayStation 4, Nintendo Switch, Xbox One, and PC. The ratings board has since deleted the entry for the game, however, a screenshot was taken prior to its removal. Currently, there is no release date for the collection.
