Battlefield 4 is set to be unveiled on March 26th during GDC. The major gaming press were sent out invites to the reveal event and Geoff Keighley confirmed the announcement on Twitter. There is a leaked promo image to go alongside that announcement. It follows the traditional Battlefield motif set by Battlefield: Bad Company 2 – the blue and orange color scheme, and a man walking or running towards the viewer. Pictures for both the invite and promo image are available below.
