Considering that comparison is too idiotic to even be worth commenting on really I'm going to say that even if Blizzard adds a landmass to the game with nothing else it is still content in the game. It might not be worth doing but it doesn't change the fact that it is still content. Not everything in the game has to be something that's story driven or character focused to be content it's just an activity or something you can engage in in the game that keeps you occupied. A landmass with nothing in it is content that probably won't keep me interested for very long other than maybe to explore it once, if there's nothing else than it's not a particularly useful piece of content but it's still content.
Apparently a lot of other people feel that way because remember the crying when Thal'dranath was removed. It was literally a landmass with NOTHING on it and people were crying their eyes out pretty hard over that.
