I still doubt they do full-on action combat, considering their style of co-op and assumed "full-party control" in single-player mode.
I'm rather curious about that their cinematic department now has over 10 people according to Linkedin. 1 director, 7 cinematic artists, 1 vfx artist, 1 animator, and is looking for
a lighting artist dedicated to cinematics. This is smaller than Witcher 3's (which was more than 20), but it seems obvious they're going for a lot of real-time cutscenes that are out of player's control.
That would be disappointing.
