CDPR have pretty much ruined all the goodwill that they deservedly got from Witcher 3. Even if all the various game breaking and immersion breaking bugs were fixed, the underlying game is an empty shell of what was promised. They would literally need to re-make half of the game to even come close to what was shown in marketing material. Maybe they'll fix it and it'll be as glorious as that E3 trailer, but I doubt it..
