I was reading about WoW alpha, beta and early vanilla when I came across two islands that used to be outside of Stranglethorn, and which can be seen in the vanilla cinematic, called the Isle of Doctor Lapidis and Gillijim's Isle.
I went on to read some more about them, and I saw a screenshot from Gillijim's Isle on wowwiki.com (http://www.wowwiki.com/Gillijim's_Isle?file=Gilijim%2527s_Isle1.jpg) which reminded me of something I saw whilst leveling in MoP.
Who rides a turtle and would be likely to end up on an island? Oh, right, that's Liu Lang, the first pandaren to leave Pandaria after the Sundering!
I really have nothing more to say about this, I just thought it was a pretty cool discovery, and that Blizzard might have had plans for the pandarens even that early in development. :)
