My guess is that it will be there at release or soon after.
Version 3.19 looks as if it blind-sided everyone - it came out of the blue for everyone here, and I suspect it surprised Aspyr as well. Aspyr were already committed to a final release sequence involving Firaxis approvals and DVD burning and distribution based on 3.17. They can build, test and release an online patch much faster, so they'll probably do that to ensure that they get a positive reception at launch.
