Thus far I have found nothing. but there are no mobs by the "Big waterfall" and the other waterfalls are so close to the dragonmaw, so i believe since dragonmaw port is phased (once it is old dark hordish and then it is new hordish) I hope we will see more about that at another point (i found rexxar in cata beta files as well so there is hoping (3 total).
