You just missed that thread: http://forum.outerra.com/index.php?topic=3349.msg39653#msg39653
. Just read from the first foof post.
TL;DR, since the last time you made your post, the team grew up (from 2 to 5) and many new features were launched (I believe you were still using the engine time to time). The engine is still in active development, and more tools and elements had to be released before they start actively working on the game (even if they are already planning things internally).
Good news, some key components for the game will be released soon (check Uriah's posts and videos to have a few examples).
