Battlefield 3 is coming to E3 to show off the first Multiplayer gameplay, if you are in the area come by and play =)
K.M also talked about some new things we will not be showing as co-op and “Battlelog”:

So why pay for Call of Duty “Elite” when BF gives you this for free? =)

Of course there are things we will not be showing at E3, including the game’s extensive co-op campaign, the introduction of Team Death Match mode and the Battlefield 3 Battlelog web destination – featuring powerful social tools, feeds and detailed player stats. Battlelog also lets you manage your friends lists, squad up, create platoons, use voice chat and follow your friends’ progress in real-time, and more. Battlelog will be available for the monthly fee of (drum roll)… zero dollars. We look forward to providing more information on these features in the near future!
