The event will be available to watch online on EA's website at 3 p.m. ET. No further details about the game were provided.
Hardline was leaked earlier today from the series' website following the discovery of a new game, "BFH," on the Better Battlelog forums. The game was listed for PlayStation 3, PlayStation 4, Windows PC, Xbox 360 and Xbox One and included four soldier classes: Enforcer, Mechanic, Operator and Professional. A logo for the game was obtained shortly after, along with images of in-game weapons, vehicles and more.
Battlefield 4, the last entry in the series, launched last fall for consoles and PC. Battlefield Hardline is one of six new games EA will apparently reveal during the press briefing on June 9.
