According to 4J Studios, Minecraft: PlayStation 4 edition was given to Sony for its final test. If the game passes the test (and it will), it will more than certain be released soon on PS4. Also, at Gamescom 2014 it has been released a trailer for the PlayStation Vita version of the game which can be seen below.
If you have the game on PlayStation 3 you can get the current-gen version for only $5 and this is available for the Xbox 360 version owners upgrading to Xbox One version. Until now there’s no release date.
