Studio updating Battlefield's social and stat-tracking service DICE has released a teaser image for the next version of its Battlelog service, which will presumably launch alongside Battlefield 4 later this year. Accessible via console, web and mobile devices, Battlelog lets Battlefield 3 players track stats and interact with friends, among other features. The debut Battlefield 4 gameplay video lists an autumn Battlefield 4 release date. Publisher EA has said that the first Battlefield 4 DLC will arrive in the form of a "premium expansion pack" available to pre-order customers at no extra cost. source:CVG
