Dying light 2: Stay Human has been delayed until 2022 | OC3D News (overclock3d.net)
 
Techland has announced today that Dying Light 2: Stay Human will not be ready for the game's planned December 7th launch date. Now, Dying Light 2 has a new release date, February 4th 2022. While Dying Light 2 is "complete", Techland has admitted that the game will require more polish and optimisation before launch. This delay is designed to give Techland's developers the time needed to complete the project to the level the studio envisions it. Techland doesn't want Dying Light 2's launch to repeat what happened with CD Projekt Red's Cyberpunk 2077, which was released in a buggy state on all platforms and with abysmal performance levels on last-generation consoles. 

Dying Light 2's new February 4th release date also moves the game away from Halo Infinite's launch window, a factor that may have taken attention away from Dying Light 2. Techland has stated that they plan to share some "exciting news" on Dying Light 2 later this month and that the game will be available to the press and content creators through a series of preview events next month. After these events, gamers can expect to hear what their favourite streamers, YouTubers and websites think of Dying Light 2's preview build.  
 
Better to delay the game in my opinion and make sure it's right than rush it out in a bad state. 

 
Too many bugs to iron out probably.

So many games this year have been delayed. I'm sure covid-19 still has a lot to do with the delays.
