WoWWiki posted a picture of Dalaran's old spot in Azeroth. It's now a gigantic hole with purple residue all over. The city has moved to Northrend, where it will be a pinnacle of Wrath of the Lich King. Click on the image above for a high resolution version.
This is really quite cool, and it's been one of the big mysteries of Wrath. It will be interesting to see what the NPCs have to say about its removal to Northrend. I'm sure we'll have that covered in the days ahead when we find out more.
Many thanks to reader Adam (no relation) for alerting us to this. Stay tuned! Lots of great Wrath coverage all weekend.
