There is an area there I found that is pretty cool, Its above the instanced caverns of time tunnel area, there is a big building, some different smaller buildings, a few trees, sort of like old hillsbrad, but much, MUCH, different.
For those of you who know the method of how to get there, just thought I'd post about this so you can have a look at it. Also if you use wow map viewer to see some other instances there are some cool new things you may find yourself wanting to explore.
