I just played the prologue. First impression: it looks nice, but it's mostly irritating.
The good:
1. It looks very good except for faces and hands.
2. No loading!
3. More gear, upgrading and crafting.
The bad:
1. Long, "interactive" cut-scenes, often followed directly by a hard or new mini-game, without save.
2. The stupid mini-games! Cool if you're an ADHD teenager with a controller, but mostly irritating otherwise.
3. The controls. Navigating around is a pain, looting requires moving around until you get the cursor.
4. The UI. More consolitis. Auto-scrolling descriptions, no overview, not intuitive.
5. The combat: randomly turning around with the mouse and keep clicking the left button works best (auto-aim). If you die: reload, meditate, use some potions and try again.
6. Potions and oils only last minutes and require meditating, so no strategy and little tactical use.
7. Third-person view only, no isometric or first-person.
8. You're on rails, and they're holding your hand.
I'll play a bit more to see if it opens up and becomes less irritating.
EDIT: I mean, when you're in a cellar, unarmed, and you just took down a guard who has a perfectly serviceable sword, of course you don't pick it up, right?
