Slime Rancher has enjoyed a great deal of success so far after releasing onto the PC and Xbox One and so it is no surprise that fans on the Playstation are hoping to see a Slime Rancher PS4 release some time in the future.
At this moment in time it would appear that there are no current plans to release a Slime Rancher PS4 version as the studio seem to be focused mainly on the PC and Xbox One.
There has been no official word from the studio regarding a PS4 release and so with the game already on Xbox it may mean that a Playstation release is unlikely.
There have in the past been some games that have released onto the PS4 from Steam such as Ark Survival Evolved and 7 Days To Die but it would appear that Sony are a lot more strict when it comes to certain games releasing onto their platforms which is a shame for fans of smaller early access games.
A Slime Rancher PS4 release is certainly not out of the question but for the meanwhile if you are waiting for imminent news of its arrival you might be better off getting it on a different platform.
