Here you can see the maps from the Mists of Pandaria beta: http://marlamin.com/gmaps/?x=77.71&y...=7&m=5&b=15464
Some of the areas can be seen in this video: http://www.youtube.com/watch?feature...&v=wx9lh_U2Dd8.
To see the text Mantis at the end of that video look for the Great Wall in the map
Thanks to Alram (Marla) for putting the map together and Malu05a for making that awesome video!
