The company that is producing the game recently posted on their official forum that the marketing/distribution element came in fairly recently, and they are concerned that they will not be able to meet demand. So, they pushed back the release date to Feb 29, and will be taking pre-orders in mid Feb for a digital download to allow them to have a controlled initial release to estimate server loads. After that, they will have a general digital order system, and then a boxed DVD software delivery at an even later time.
