There are only French previews so far but here's what I've got from it, in bullet points.
-Turn-Based (Think original Fallout), hexagon shaped tiles, still fast paced
-Stats ala hack'n'slash, strength, intelligence, vitality and dexterity, many equipment slots.
-2 main characters, a man who's an ex-prisoner and a girl who has been freshly resurrected
-Can be played solo or in co-op
-Can interact with a lot of objects, using buckets as armor, brooms as weapons etc.
-Can use spells to affect the environment, ice magic to freeze water, lightning on wet opponents to boost damage etc, kinda like Magicka in that regard.
-Both characters have a role during conversation, even in co-op both players will pick choices so there's no '' leader '' making all the choices while the other players simply watch.
-One character can talk to an NPC while the other character sneaks behind to steal something or access a restricted area
-Dialogues are of the same quality as other Divinity's game, so humorous and witty.
-Open-ended
-No level-scalling so while you can go anywhere you might still get ****ed badly if you're not strong enough
-No classes, you pick the skills you want to customize the characters as you see fit.
Looks promising I say!
