Save the date for a potential Battlefield 4 reveal
Although the invitation doesn't specifically mention Battlefield 4, the color palette is similar to that of Battlefield 3's box art. And yes, there's also the signature lens flare. Given EA's track record at GDC, this honestly doesn't come as much of a surprise; the company revealed Medal of Honor: Warfighter at last year's GDC.
The presumed reveal is set to take place on March 26, 2013 at 7:00pm at a movie theater in San Francisco, although the address has been blurred. Be sure to check back around then to see what this is all about.
