DICE works on both BF3 and BF4
Battlefield 4 is coming, with a beta scheduled to begin next fall, but DICE assures fans that doesnt mean a premature end to support for Battlefield 3.
Following up on earlier pledges to the same effect, the developer said on the official Battlefield blog that it intends to continue with BF3 support past the beta, continuing even after BF4 is released. "We are committed to providing an excellent Battlefield 3 experience well into the future , past the releases of Aftermath, End Game, and Battlefield 4," a representative said on the blog. "DICE is continuing its work on Battlefield 3 alongside Battlefield 4."
Of course, theres no way of telling what that "work" will entail following the release of Battlefield 4. Its certainly an impressive claim nonetheless, one that we hope isnt equivalent to pre-selling us some exclusive bridge DLC.
