The Witcher 3 has been delayed until February 2015. According to an open letter the developer posted on thewitcher.com, they state, "We could have released the game towards the end of this year as we had initially planned. Yet we concluded that a few additional months will let us achieve the quality that will satisfy us, the quality gamers expect from us. Consequently, we have set the release of The Witcher 3: Wild Hunt for February 2015."
It sounds to me that they essentially just need some more time to polish the game and put in finishing touches. I personally remain very excited, and can't wait for the release. See the whole original letter at http://thewitcher.com/news/view/729 --Drake72 (talk) 22:55, April 30, 2014 (UTC)
