The Techland team working on Dying Light announced a bit of a delay for the game today. It's now been pushed back to a February 2015 release window. This is a delay of a few months past its original plan..
When we started the development of Dying Light, we were committed to innovation. We wanted to give you a freedom of movement unprecedented in open-world games. After many improvements and months of hard work, we have now come so close to realizing our initial vision we feel we cannot stop before it is ready.

We believe the Natural Movement element of our game will change what you expect from the genre, and we don’t want to sacrifice any of its potential by releasing too early. This quality-focused thinking underlines all our development choices and we hope you share our belief that the gameplay must always come first.

The new date ensures that we can fully realize our vision of an innovative open-world game. We won’t need to make compromises or trade-offs on any of the five platforms we’re working on. For you, it means an outstanding, original game that makes the wait more than worthwhile.

Techland expects to show off Dying Light again at E3 next month, with more feature reveals coming in the months ahead. Dying Light is still slated for release on the PC, PlayStation 4, PlayStation 3, Xbox One, and Xbox 360.
