Ok as we all know Night Elves Descended from Dark Spear Trolls many thousands of years ago. However reading though some of the stuff for the up coming content I can't help but notice something odd.
Female Mogu http://www.wowhead.com/news=209326/5...1:46975:0:10+0
What the first image shows is a hulking troll who looks a bit like he's in Mogu gear, also he looks a bit like a Mogu.
In the second image we see the female Mogu looks just like a female troll. So my thinking is the curse of flesh effects Mogus by turning them into Trolls.
Maybe I am reading to much into this. But it really is starting to look like they plan to drop that soon.
Also I think there is a goblin connection as well see image
Look at his face. And compare http://images1.wikia.nocookie.net/__..._cataclysm.png
