I was expecting a Divinity 3 game, too, but I think the two new projects look amazingly good ^_^
I'm looking forward to Original Sin, especially. Not only because it shows clearly that good-old classic RPG is still marketable, but because it's some kind of a prequel to DD. We still have some Divinity universe to explore, again.
I'm not sure what to think of Dragon Commander, though. It looks great, yes, but I'm not sure if its my kind of game.
