And the second is at The Guild Hall:
About the size of GW world :

A: At release, there will be 25 missions, 60 to 70 explorable areas, and around 9 maps for the GvG with different objectives like killing other's guild lord, controlling resources or holding a place. [he had already showed us Arenas and Tombs]
