That would be a convenient explanation had that trailer been at an E3 show case while the actual game was still in development years away from being done. It doesn't fly here since that trailer was right before a mediocre at best sized DLC dropped AND the items are in the armory. They should have/would have been removed if removed from game. That explanation does not fly. It seems to me that you would make an argument that the sky is not blue somehow, even though it is. Like, there would be some long Reddit style thesis with some nuanced argument trying to stretch for it.
