Not_you: A huge retailer from Denmark claims that the game will be available december 2018 (see attached image). I find that very hard to believe.
I found another site that had a pre order with a release date listed as December 28, 2018.
When I learned the game was going to be a FPS, I was devastated. I do not generally play them at all. I may pick up the game at a later date, just to support CDPR and GOG, but not right away. That aside, when I read on some sites that the game is larger than Witcher 3, I was quite surprised. I can only imagine the hours that could be spent in Night City.
Edit: Fixed typo.
