According to Battlefield’s official Twitter, “big announcements are coming soon”. When I read this tweet, two posibilities came into my mind. EA will either make a presentation at today’s Xbox event, or they will present the hole game and features at E3 2013. Also, it could be both, as they want to keep the suspense at maximum levels before releasing the actual game.
We can also take in cosideration the rumour spread a few months ago that Microsoft is working a deal with EA for some exclusive deals or footage. It could be just a time limited DLC, like it was done with Black Ops 2’s DLCs or maybe much more.
