In much of the gameplay coming out now, people are showing that there is a separate suit display room in the Batcave that is seemingly for the DLC suits. In this room, there are five more displays, each with seven slots, which fits the DLC idea. There are three displays that are connected together, presumably being for the Legacy Collection packs, and two more separate displays. One is likely for the Sinister Pack coming in September, but who knows what the other is for.
