The Battlefield and Origin team made expansion packs for BF1 and BF4 free in the past. We're not aware of any current plans for another promotion at this time.
Battlefield 4 Premium is included in Origin Access Premier (PC) and EA Access (Xbox One) memberships. You can sign up for monthly or yearly memberships which includes access to a library of games and be the first to play the latest games that are set to release. It's also still available to purchase standalone as well for the Xbox, PlayStation, and Origin store.
Thank you for being a fan of the Battlefield franchise!
