Earlier this morning CD Projekt, the developer behind the title sent out an open letter announcing the delay. The dev stated that it was very possibly for them to meet the Fall 2014 release but the additional month will make drastic improvements to the title setting it apart from all other RPG's.
The title is being developed for Next-Gen consoles as well as PC, it was stated earlier this year that the game will not be released on Current-Gen consoles this may be due to the fact that the title is said to be near maxing out Next-Gen consoles, even trying to fathom that is ridiculous.
For those who don't know The Witcher 3 is being developed on CD Projekt's RedEngine3 and is one of the most visually advanced games currently announced for Next-Gen consoles. The non-linear story is created based off the players decisions giving a memorable and different story each time it's played. The game follows Geralt of Rivia, a genetically enhanced human trained to fight monsters with special abilities varying from each Witcher.
The Witcher 3 is said to provide gamers with over 100 hours of gameplay will be released February 2015.
