It’s possible there’s a connection between this and the news that Battlefield: Hardline is being delayed until 2015, though it’s a thin possibility given that DICE is the studio behind BF4 and Dead Space developer Visceral Games is working on Hardline. The cops vs. robbers taken on the Battlefield was originally scheduled for release on October 21, with Final Stand expected to arrive before that. It’s possible that DICE resources are being diverted to help Visceral ensure a timely release for Hardline.
With BF4 Premium subscribers just sinking their Dragon’s Teeth into the latest expansion of Battlefield 4 (and non-Premium members still waiting), this delay gives the new add-on more time to breathe.
