The text, pictured below, appeared to confirm how the game will perform despite Ubisoft's silence over how Watch Dogs will compare across different platforms.
"Hack everything as you make your way through Chicago's underground as you experience Watch Dogs in a way that only Sony can provide, at 60 Frames Per Second in 1080p," the site formerly read.
But now any reference to resolution and frame rate has been removed from Sony's website.
Interest in resolution and frame rate performance has endured since the launch of the PS4 and Xbox One in November. Since then, the PS4 has demonstrated an advantage over Microsoft's console, with titles including Battlefield 4 offering better performance on the PS4.
Watch Dogs cinematics animation lead Lars Bonde recently confirmed that Watch Dogs will run at 1080p on PS4, but did not offer details on resolution for the Xbox One edition.
Meanwhile, an Arab Gamer report claimed recently that Ubisoft had revealed specifications for the game during a Watch Dogs press conference: PS4 (1080p/30fps), Xbox One (960p/30fps), PC (up to 4K/framerate varies).
Ubisoft released some high-res Watch Dogs screenshots earlier this month, showing in detail its virtual depiction of Chicago's towering skyscrapers and busy streets. A recent Watch Dogs gameplay video showed multiplayer modes and fantasy 'Digital Trip' side missions.
