In EA's conference they discussed with DICE on the nature of their new premium service, Battlefield Premium. This is essentially BF's answer for CoD Elite. Like CoD Elite it will feature content that would enrich a fan's experience in a number of ways.
Members will get access to unique camo, dogtags and knifes, mostly vanity items. What you would really pay the price of $49.99 for is the 2 week early access of DLC packs. Back to Karkand, Close Quarters, Armoured Kill, Aftermath and End Game will be available in this service and separately. Below is the trailer that they showed, the same trailer that was leaked recently.
