"You get what was advertised" is a bit dubious. There are always some parts of the games left a surprise, and I'd bet most people expect at least a little more than what they are literally told as a result. And what counts as advertising? The packaging? Media adverts? Official sites/blogs/twitters/etc.? Interviews? Hell, this Day 1 DLC came out of nowhere. Not advertised at all until the day of.
