Personally, I firmly believe they haven't done anything, aren't actually planning on doing anything, and are waiting until this whole thing blows over before they quietly announce that we won't be getting the DLC at all.
When I went to pick up Assassins Creed 3, this seems to be the popular belief with everyone in the store.
If they think it's going to blow over with no announcements and it's all going to be all ok. Well that's just wow xD
I agree with it as well. They have nothing to show us, therefore I have no reason to believe they have done anything, I just want closure on it :3
