We are in the delayed season right now. Final Fantasy VII Remake, Marvel’s Avengers, Dying Light 2, Marvel’s Iron Man VR and Cyberpunk 2077 have something in common. All those games have been moved in the calendar recently.
The game produced by CD Projekt has been showed to the mass in a very specific way, very meticulous. Rockstsar-esque. According to Borys Niespielak, a polish insider defined as the Jason S. of the country, Cyberpunk 2077 has been delayed due to its poor performance on current gen consoles, which are not powerful enough to run the game properly.
I have to admit that this is not extremely surprising considering that the game have not been available in a playable way in any show or event. Gameplays have been conducted always by CD Projekt staff. Therefore, this info is plausible.
