Also, I'm pretty sure for each expansion they've developed so far they had an extensive list of features, some of which they know they're gonna cut, no matter what. Discussions such as this thread, can help them determine which ones.
Obviously I'm not talking about changing theme of the entire expansion. When I say they could adjust something, I'm talking about mostly how they're gonna market this new expansion. If they see that some speculated feature meets strong negative feelings from the community, they could remove it from the announcement, replace it with something else that also fit this expansion and on their list to do. That removed feature can later be 'fixed' according to feedback they have or maybe scrapped for good.
