From what was said I understand there is fixed camera scenes only. Now you mention devotion stuff. I am not sure I understand what are you talking about.They did hire developers. They made the game bits, and they did the animation bits. But you still have to put those animations in the frame of a game. That's why they held the devotion stuff til last, because those are outside the frame of the game, and are just pure cinematic lovemaking.
Also suggest you watch the 'what's coming in 1.0' video, they address the grind.
I know they say they adressed the grind, but didn't see any user comments regarding that issue.
