Either they wont or they cant, many years and 2 billion dollars later, it's funny to think the franchise doesn't have an item management system and they have to rely on fan base website. Streamers gonna get pissed once they realize they need to grind for 30 new weapons and have no free slots in their vault because they had to keep all their godrolls somewhere. 6-8hours a day streaming and grinding will fill up that vault real fast. They might not advertise the expansion favourably.
