Neverwinter PS4 Version Has Neat UI, and the Potential to Be a Good Console MMO
First and foremost, the UI for the PS4 version is completely redesigned for console control. It has a typical console layout for skill/item slots, which clearly tells you which button is aligned to which skill/item. On the other hand, the game uses the palette UI for skills, a common design for console controllers. Although there aren't many innovations and surprises, there are smoothness and simplicity.
The developer told me that they won't make any change for gameplay content for the PS4 version because they believed console players wanted the same thing when they sat on the couch playing the game.
The second thing to be mentioned is the update cadence for the PS4 version. I was told that the PS4 version will get content update about one week later than the PC version, and will be at exactly the same pace as the Xbox One version.
Unfortunately PWE didn't announce the Neverwinter PS4 version release date. So for now we just know it will launch this summer.
