There's an @OuterWorlds team still working away on something at Obsidian. Future support and DLC sounds likely. "People are obviously loving Outer Worlds and we made it because we love it, so now we get to keep on doing things to help support [it]."

In addition to post-release Outer Worlds support and Grounded (the new game) development (a very small team), the rest of 185-person @Obsidian is working on new games (plural). How many? "More than one, less than forty."
