Lynn's right - very little we can share at this moment though we did promise that we'll try to be much more open about it during development., For now what I can tell you are but rather generic things such that It's an action RPG, it's in the Divinity universe, it's different yet not so different, the concepts behind it are pretty cool with a few things in there that we think are quite innovative.
It's being made by the same team that brought you DKS, and the designer brief is that every single quest in there has to be a real choice. The engine won't be the same, we know what it will look like, the concept artworks look quite nice and I quite a appreciate the visual style, the story is quite different from what we did so far but interesting I think, the character development system on paper looks very cool and is again classless, combat looks like it should be fun and we're thinking of making it top-down again like the first game. The scope is open for the moment with the initial brief being that it should be a 20 hour RPG with the ability to add chunks of 10 hours to it depending on how the market evolves and if we can convince people to invest in letting us create more content.
