The XCOM website announces a delay to XCOM 2, saying the this is now expected on February 5th. Firaxis' sequel to XCOM: Enemy Unknown was announced with a November release window, but now they admit they need more time. Here's word:

We want to give you an update on the release date for XCOM 2. We’ve set a high bar for the sequel and the entire team has been working hard to make sure we deliver a great follow-up to Enemy Unknown. We just need a little more time to make it the best possible game.

With XCOM 2, we want to have more depth, more replayability, and more investment in your soldiers and this extension will give us the time we need to deliver on our promise to you.

We appreciate your patience and continued support as we move towards February. Good luck, Commander!
