The trailer definitely was something.
I think it will split the fanbase probably and its a good thing for kindling a long lasting discussion. Divinity has always been a very brutal, gory and violent game (Kniles the Flenser from DOS immediately comes to mind for example), yet the series hasn't really received a high enough level of promotional material to depict this violence in, not a stylized, but a truly horrifying way.
I have trust in Larian and looking forward to more details.
I am very happy to see another entry in the series!
