The Taiwanese Rating Board rated (link doesn’t currently work, but it did, promise!) An unannounced title called Castlevania Advanced Collection for PlayStation 4, Xbox One, Nintendo Switch and PC. Konami has yet to officially announce it, so no details are known, but the name implies that it should include the Castlevania titles originally released for the Gameboy Advance.
This unannounced collection was previously rated by the Australian Rating Board in June of this year.
At the time, three of the Castlevania games in the franchise have been released for the Nintendo handheld: Circle of the Moon, Harmony of dissonance, and The air of sorrow. The third of these games is particularly well regarded by the fandom and had a Nintendo DS sequel called Dawn of sorrow.
According to Australian rating details, the developer of the collection was M2. The company is known to have worked on many projects emulating older titles, having also worked on Virtual Console and Sega Ages re-releases. In addition, they also worked on the Castlevania anniversary collection and Contra anniversary collection.
We will keep you posted on upcoming announcements and the latest news on it. Castlevania Advanced Collection when Konami officially unveils this project and its actual content. For my part, I cannot wait for this hopeful eventual announcement.
