Looks like the PlayStation 4 Minecraft version has been delayed according to 4J Studios latest tweet on the development process.
Minecraft: PS4 Edition was sent over to Sony to pass the tests to bring the game to the system. Unfortunately the studio has found a few issues within the test which is making the developers go back and fix the last bit of errors.
There has been no other news on the other versions of Minecraft either. Both the PlayStation Vita and Xbox One has been last mentioned on August 12 which 4J Studios stated that they are currently fixing bugs on the different versions.
