They did mention that they would be doing major updates at the end of each season that lasts 3 months. I think the updates will be separate to DLC but we will probably have to wait until the first DLC drop for the update. I do agree that we have nothing more than a token response and vague promises but at least the communication has begun, they couldn't exactly wait much longer with the forums ablaze and major media outlets covering the rampaging player base without doing irreparable damage to their already stellar reputation.
