A new trailer was accidentally posted on Battlefield's Official YouTube Channel earlier today, and was taken down minutes later. The trailer (above) confirms and shows many new items that will soon be available for download as DLC for Battlefield 3. Many questions still remain unanswered, such as How much will it cost? and When will players have access? We do not know for sure right now, but we will tomorrow during EA's Press Conference at E3 2012.
