Korea's Game Rating Board has issued content ratings for unannounced PlayStation 4 and PS Vita versions of The Unfinished Swan according to a Gematsu report, suggesting that the 2012 first-person puzzler is due for a cross-platform release.

Currently available exclusively for the PlayStation 3, The Unfinished Swan is a (mostly) monochromatic adventure game in which players splatter their solid-white surroundings with black paint in order to reveal environmental clues and hidden passages. Joystiq's Richard Mitchell awarded The Unfinished Swan four stars in his review, recommending it for players who are looking for "a little less logic and a little more fascination" in their puzzlers.

Neither publisher Sony nor developer Giant Sparrow has issued a statement regarding new ports for The Unfinished Swan.
