I don't know where you got this opinion. I think most people from Poland have high hopes for Witcher. Also never seen that delay was the problem.
The only problem people have and should have is the issue that CDP won't use some ps4 functions only because they don't want this game look better on ps4. Then they give more elements (cards) to xbox one CE. First they want to give exact experience in every platform then they give more ''content'' to xbox one users. But it's more of a problem for PS4 players. It's not fair but let it be.
People just think (and they could be right) that CDP got financed from microsoft for more exclusive content and so game wouldnt look better on ps4.
Anyway i don't think it's really bad issue because it happens all the time in game industry. I really didn't found much hate on CDP from ''my'' people
Of course there are hateful trolls but they happen on reddit and other sites too. Nobody likes kids like this.
