The unannounced collection was first rated in Australia on June 18, then again in Korea on June 25. While the Australian rating listed the game as “multiplatform” and the Korean rating for PC, this is the first time console platforms have been specified.
The collection will presumably include the three Castlevania games released for Game Boy Advance from 2001 to 2003: Castlevania: Circle of the Moon in 2001, Castlevania: Harmony of Dissonance in 2002, and Castlevania: Aria of Sorrow in 2003.

The newly published description also confirms that it includes Castlevania: Circle of the Moon in 2001, Castlevania: Harmony of Dissonance in 2002, and Castlevania: Aria of Sorrow, as well as Castlevania: Dracula X. There is also a “Rewind” function and other handy features.
Update 09/23/21 at 8:30 a.m.: Castlevania Advance Collection has been rated by the Entertainment Software Rating Board. Here is its description:
This is a collection of four classic Castlevania games in which players battle monsters and attempt to overthrow Dracula and his minions. From a side-scrolling perspective, players traverse platform environments and use whips, boomerang-like blades, and grenades to kill fantastical creatures (e.g., vampires, demons, harpies, ghouls). Several enemies emit splatters of blood when injured or killed, and some levels / environments contain larger depictions of blood: tears / pools coming from a statue; a bat crushed in a giant’s hand; a figure impaled on a stake. A handful of small female demons / monsters are depicted topless. The word “bastard” appears in the dialogue.
