If you are talking about the end of jan, feb time?
Combat viewer I suppose is the big one they have talked about, but before any more races get released i'd rather they do the next map size as it's getting way too crowded for me.
Then after that AI is the main thing stopping me enjoying the game, if they are aiming for the fun factor that would be my main concern, giving each AI race it's own unique competent AI (doesn't have to be great just starting to show signs of intelligence).
