In a new interview, Treyarch's Senior Production Director Yale Miller explained that the studio is not aiming for exclusively "realistic" cosmetic items in Black Ops 7, but wants them to "make sense for Black Ops 7." In this regard, the developers have abandoned several major collaborations with well-known brands.
We had offers from big brands, but after discussions, we turned them down because they just didn't fit. Our goal is to create content that we can wholeheartedly call part of Black Ops
As an example, he cited the mannequin skins from the Nuketown Block Party event, which, while not realistic, "feel appropriate for the game."
Treyarch has not completely ruled out collaborations, but in Black Ops 7, it seems they will only include those that harmoniously fit into the spirit of the series.
