Yesterday it became known that the hard-core RPG Demon's Souls again passed the rating classification of the agency ESRB on the initiative Atlus USA. The game servers were closed somewhere half a month ago. It is logical to assume that the company is preparing for the announcement of the reissue of the game.
Also should remember yesterday's statement Bluepoint Games, in which the studio announces the work on one more major remake. So the next title of the re-release of Shadow of the Colossus may well be a remake of Demon's Souls.
