Here's the examples from the Pandaria trailer by the way.
Man, Kun'lai in the announcement trailer looked so interesting and visceral, look at all this greatness. Such a shining example of Quality footage. They would never get away with so many re-used assets nowadays, a true Landmark in a beautiful l--.. where's the wall? Huh, isn't there supposed to be a ruin there? Oh wait, where's ---
Note, all the Landmarks here, they showcased the Valley so amazingly. Look at the centre of Pandaren crop trade, Halfhill a--... well, uh.. just assume the tree isn't in the way. And ignore the untextured building on the right.
Edit: Kun'lai is so funny too, because later down the line they actually have a good landmark shot of the Monastery, but the footage sets a precedent that you'd still be able to see the assets if they were there, even with the old draw distance and the whole monastery portion of the mountain's just missing.
