EA has launched a new teaser website for the upcoming announcement of Battlefield 4, featuring the chance to wipe away virtual rain from your screen to vaguely see a tank in the background. The interactive site reveals that the first ever gameplay trailer will be revealed on March 27th, the day after what is presumed to be the official announcement from several invitations sent out to US press last week.

Currently little is known about the upcoming FPS title, however yesterday a rumoured leak suggested various design changes including enhanced destruction and multiple platforms releases might be found in DICE's next title. It is not known exactly when Battlefield 4 will be released, however it's quite easy to presume more will be revealed on March 26th and 27th at this years Game Developer Conference.

According to the teaser website, those who log in with their Origin ID before the reveal will be able to grab themselves a unique dog tag saying "I was there" and also states that the "more who log in, the more we'll reveal."
