As I recall, Swen said, when asked if their next game would be in the Divinity series, that he couldn't confirm or deny, but that it would be different from what you think it is, but still familiar. I'm thinking maybe a full 3D action RPG set in the Divinity universe or something, based on that statement of "different but familiar".
I'd be shocked if Xbox managed to convince Larian to make a Fallout game. Even if it were to happen, I would hope that it wouldn't be the only Fallout game in development, a Larian Fallout would likely be more in the Fallout 1 and 2 style, which wouldn't really satisfy the Fallout 3/NV/4 fans. The only way that a new Bethesda style Fallout gets released at any point before probably 2035 is if Obsidian makes one, or if Bethesda finally expands into multiple divisions each focused on one of their 3 IP. A new Fallout 1 and 2 styled game would be great for the fans that have been waiting for a traditional Fallout ever since the Van Buren build of Fallout 3 was cancelled, but it shouldn't be the only Fallout game to release in the next 10-11 years imo.
