I don't know what the developers have been doing for the past year but back in February two new DLC items were added to the Steam database. The codenames for these DLC are 'Hawk' and 'Breeze'. These names don't necessarily have anything to do with what will be in the DLCs but we could see them release in the next few months.I guess it's a little disappointing. I had a premonition it might be like this - that by posting an ultimate pack, they were subtly giving away the fact that "We're not going to work on this any more."
But it would have been nice to have a few more little things.
