want gonna happen talked about that in stream 100 or 101 cant remember but he said he rather works on the game mechanics as those things like games which got xmas dlc's but the game doesnt even work fine so i guess its much better this way for the moment (:
Firefly said something about not doing a christmas event because it would only be a once a year type of thing and he'd rather much work on adding new permanent features to his game.
Just to be clear, those are not his exact words but it is along the lines of what he said.
