Capcom has now officially revealed the release date of Okami Remastered, it is December 21. The game will cost 2,990 yen plus tax according to Ryokutya2089.
There is no info on the platforms for now but we know that the new Okami HD version, titled Okami: Zekkei in Japan, will have HD and 4K support with added elements from the original Okami. Limited edition version will also be available for 4,990 yen.
We have had some reports in the past showing Okami HD ratings from South Korea, which showed the game listed for PlayStation 4, Xbox One, and PC, but before Capcom gives an official statement we can only keep guessing.
