Perhaps that is how long they are "popular" in a quilt store. After that, customers start thinking that the LQS isn't the place to shop because all the stock is "old". I have been in a few stores where the same fabric has sat for months and months. I understand keeping the TOTs and some of the basics in, but when they very obvious prints, they need to move quickly to keep a shop competitive with on-line stores. I won't go to the effort to shop in my LQS if I don't think I will be seeing new prints/designs relatively often.
