The folks at WotLK Wiki sent us a note that they've got an interactive Northrend map
up and running. It's nothing too surprising (they basically just put all of the map screen maps from the beta together), but it is in a nifty Google maps interface, so you can drag, click, and zoom around the new landscape at will. And of course, the pictures don't mean too much at this point -- of course big landmarks like The Nexus and Ulduar stand out, but it's assured that actually seeing these places will be much more amazing than just seeing their flat representations on the map.
What's really interesting, though, is going way back to the beginning and comparing this map
to all the different versions
from Blizzard's planning stages. Though a lot of things have been added in to fill in all the space, they've really been faithful to the overall design since the beginning. Even the Warcraft III maps
match up pretty well. Blizzard really sticks to their mythology, and that's probably at least one reason why fans enjoy exploring it so much.
