Decisions like when to announce a project come down to marketing decisions. And marketing at Disney is notoriously mercurial.
Often times, marketing wants to, and the executives, like they do to other leadership in different departments tells them no, they as top brass know better.
This happens a lot within this company to where WDI, Marketing, Retail design, procurement(and so on) wonder why they were hired as experts in the first place.
Marketing based decision, but not marketing department.
