Yes my friends, EA and DICE has just announced Battlefield 4, and I am going to share what I know already, and some videos/links.
-First, there is an exclusive "I was there" dogtag for use in battlefied 3 for watching the Battlefield 4 teaser videos
-Some rumors that Premium Battlefield 3 players will have access to Battlefield 4 Beta, but is unconfirmed.
-This video shows 17 minutes of Battlefield 4's single player campaign
Some things I noticed from the video-
-Vehicle models of the UH-1 helicopter, the MI-28 attack helicopter and the Bandit jeep are extremely similar to Battlefield 3's models, as well as the character models of the Russian soldiers.
-The gun used by the player has a side mounted ironsight, which would be amazing in multiplayer, and would really allow players to use higher zoom scopes without being nearly useless in CQC.
If anyone notices anything I missed in the video, please let me know!
