Approximately 2 years from now, worth the wait from what people are saying to be honest. Everyone is saying how EA will manage to screw something up, but with this amount of time, I'm sure they'll put out a great game. I'm also pretty sure they have been working on this for quite a while now, but if they manage to release it and ends up being horrible, I believe that it will be the last of EA. Again, this is just a guesstimation of when it will actually release announced by EA.

Given how little Electronic Arts and Battlefield developer DICE showed of Star Wars: Battlefront at E3 2013, a release date far, far away for the Star Wars-themed shooter shouldn't come as a surprise. At EA's annual meeting of stockholders today, chief financial officer Blake Jorgensen offered a clearer window for Battlefront's release, pegging summer 2015 for launch.
