Update: unfortunately it was not to be. Rebellion sent a statement our way, clarifying that they're just in the dark as we are about upcoming PS4 system updates, and the hint about custom PS4 theme was basically just a guess on their part. You can read the statement in full here.

You can also read the original article below.

One of the most requested features for the PS4 is the ability to set a custom wallpaper besides the themes provided by Sony, and Zombie Army Trilogy developer Rebellion might know about it something that we don't, or at least that's what the game's official website seems to be indicating.

In order to get to the rather interesting hint, you have to follow a slightly convoluted path. The "free content" area of the official website will require you to sign up for a newsletter. Once subscribed and confirmed, you'll be redirected to a new page with a set of wallpapers, including one for Xbox One and one for PS4. Of course, the caveat is that the PS4 doesn't currently support custom wallpapers.

Yet, the page reassures the visitor, as you can see in the screenshot below.

Note for PS4 users: The ability to set a background should be available in an upcoming System Software update.

Of course, considering that this isn't an official announcement by Sony, we should consider this just a rumor, but it's definitely an interesting one. The PS4 didn't have a major system software update in a while, and we might possibly hear something about this soon.

Below you can find the wallpapers for PS4 and Xbox One. As you can see, the only difference between the two versions is the logo. The PS4 version appears to be a simple 1080p wallpaper like any you could use on your PC (and as a matter of fact, you can).
