Kaiser comments this is not the The World of Warcraft: Burning Crusade’s World Map, but it does show the Sunwell Plateau, north of the Blood Elf starting location: Eversong Woods. Bloodmyst and Azuremyst are missing in this pre-Burning Crusade map.
Compared with the World Map of Wrath of the Lich King alpha unveiled at the Blizzcon 2007 Panel, the Sunwell Plateau wasn’t present at that internal build.
UPDATE: An Alpha tester, Dark Entropy @ Skullcrusher, contacted me to correct certain things. The Big isle in the center of the map is Zandalar Isle. The two small isles near Stranglethorn Vale shown in the Wrath of the Lich King map are from the Alpha build: Gillijian Isle and Dr. Lapidis Isle. These aren’t mentioned on the Warcraft RPG Books to my knowledge.
Below is a map from White Wolf Publishing’s World of Warcraft RPG: Lands of Mystery (2006) showing the South Seas isles: Tel Abim, Isle of Kezan (Undermine), Zandalar Isle, Plunder Isle and Broken Isles.
