The Legend of Dark Witch Renovation

An unnamed game in The Legend of Dark Witch series is slated to release in Fall 2019 for the Nintendo Switch, presumably replacing Brave Dungeon: Seigi no Imi (which is likely to miss its projected 2019 release date) as the franchise's 5th Anniversary game. Oddly, while very little is known about the game itself, several side features have been discussed.

=Known Info=
 * The section of the 5th Anniversary site covering the 2019 Dark Witch game features a blurred portrait of Blad, suggesting that she will play a role in the game.
 * A screenshot of the game's save data screen was shown via Twitter with Japanese, English, and (Traditional?) Chinese variations.
 * The game's Sound Test will cover the entirety of the game's audio, including music, sound effects and voices. There are "IronLand", "SnowLand", and "SandLand" sound effects
 * Avoid Runner will return from Brave Dungeon, possibly with new features.
 * An image of a bound ring was shown relating to this new game.
