It really isn't. The fact that there have been no more announcements is a good indication that it's either not being worked on, or has a long time to go. And your post is a great example of why they shouldn't announce stuff unless it's ready for release yesterday.
As far as I can tell, Vive la France was released ten months after the initial announcement. New Mexico was announced six months ago, and people have already been crying for months over how it never gets released. ATS was released two and a half years after the initial announcement, and even then everyone cried over the small size of the map. (I'm inclined to agree with them on that, but that's another topic)
Lastly, you will rarely hear a company say "no". I'm no marketer, but I assume it's in their interest to keep the customers' hopes up. It's usually "something to look into in the future". At most you might get "no plans at the moment".
