Big zones?

[Midnight]

I was looking at the new Burning Crusade interactive map that Blizzard posted, and I noticed that some of the zones have two outposts for Alliance and two for Horde. One of them has this AND two neutral ones. This got me thinking, how big are these zones going to be???

Beyond the Dark Portal lies Outland, the broken remains of the Orcs' homeworld, Draenor. Amid the ruins of this world, the survivors of the cataclysm are trying to rebuild, and in other parts of Outland, life continues to thrive. Those brave enough to make the journey through the Dark Portal will find new allies and enemies, as well as limitless adventure beyond an untamed horizon.

We’ve just released an interactive map showing all of Outland’s dungeons, Alliance and Horde settlements, faction bases and neutral cities as well as new screenshots of each region. Check out the interactive Outland map now!

when you click on the lower left continent, you see a picture of Nagrand. if you compare that picture with the corresponding part of the map, i personally think the map won't look that huge :S
i think zangarmarsh is about as big as Swamp of Sorrows

I think the presence of two cities a piece is interesting and indicative of a larger scale. But who knows...

outland suppose to be about 25% percent of the current game world
