Do you think that's any different from what might happen inside Blizzard between developers/designers and managers (maybe from financial or marketing departments)?
Yes. Because Blizzard earns most of their money from the subscriptions and not the release of new products. So there's much less necessity to get expansions / new product out the door until they're truly ready to go. The financial and marketing departments work with this fact, not in spite of it.
The same could not be necessarily said of Hasbro to Wizards.
