While exclusive deals sometimes run out, and thought to be exclusive titles appear on other platforms, Oddworld: Stranger's Wrath is a bit of a special case. The game was originally meant to be published on Xbox by Microsoft, but as Microsoft focused on Xbox 360 they dropped developers Oddworld Inhabitants, and EA ended up publishing the game on Xbox in early 2005.
Since then Oddworld Inhabitants transformed from a game development studio to a studio that designs movies and games (but that has yet to actually get anything out there). And today it was announced by Just Add Water (Gravity Crash) that they are porting Oddworld: Stranger's Wrath to Playstation 3 and PSN for release next Easter. It will feature 720p graphics and Move support.
