There’s no PS5 edition of Minecraft because Sony wouldn’t send Mojang a dev kit

Xbox boss Phil Spencer says the reason Minecraft has yet to release a native PS5 edition is because Sony was “reluctant” to send the team a PS5 dev kit.

Without a dev kit – that is, the specialist equipment given to developers to test their pre-release builds before they're released and sold to the public – Minecraft developer Mojang could not get a head start on the PS5 version, putting them “at a disadvantage”.
