Did the Christmas news release not say that Normandy had to come first before the Caucasus update??
Edit no it was the 2.5 delay announcement: "We have determined that the DCS World 2.5 update will not be available in 2016 as we had earlier hoped. This is mainly due to additional work needing to be done of the Caucasus map update, and we don’t feel it can be accomplished within the next two months at a high level of quality. Before we can complete this map update, we first need to finalize and release both the Nevada map update and the Normandy map. Those, along with the Spitfire, are now our highest priorities. Once the Nevada update and the Normandy map tasks are complete, our map team can return to the Caucuses map and move the 2.5 closer to an Open Beta release."
