Has anyone heard anything about additional DLC coming out after Slingshot?

On October 25th they announced two single player DLC packs, the first of which was Slingshot released on 12/4, but they've been quiet since then. The official XCOM Twitter account is inactive and Firaxis doesn't have one that I can tell. I know 12/4 was less than a month ago, but I'm curious what's out there on the horizon.

Heard nothing from them yet....still curious as to what new DLC should they add. Though if they made DLC inspired by Terror From the Deep, that would be awesome. :)

There were some weird Steam Achievements that suggested Terror from the Deep-like content.

Considering how's there's stuff they've dummied-out of the game (like the parameter settings), I'd be surprised if they didn't smother this bitch with DLC, like they did with Civ5.

A new year means new games to play. Keep XCOM relevant. I'd like to see more maps/weapons/armor introduced as well as more enemy types and research options during the campaign. The equipment selection is very simple now. I'd like to be able to make more pro/con choices when selecting what equipment to bring. I wouldn't mind a set of new faces for the troops and more customization options in general. I think that they shouldn't wait too long to build on what they have established.

Or XCOM 2.
