Sony has revealed you won’t be able to customize your own wallpaper on the PS4.
Sony Worldwide Studios president Shuhei Yoshida confirmed the somewhat bad news on his twitter account earlier. A neoGAF user posted the conversations where two fans asked similar questions. He said “no” in regards to changing the wallpaper/background of the PS4.
This is boring, but nothing a simple firmware update cannot fix. This is odd considering you can pay for attractive themes and wallpapers for the PS3. Hopefully you’ll be able to alter the wallpaper on the PS4 in the future once Sony realizes how boring a default background can be for some people…
