I am not concerned because i never set my expectations too high.
I would even be happy if the game only reaches half of the quality The Witcher 3 has because in that case it would still be better than 90% of what's out there on the market.

But from what we have seen in the gameplay demo and the deep dive video, quality wise, this game can't even fail anymore as long as the rest of the story and world design aren't a disaster.
