WWII Eastern Front
qwert
The most controversal map in history! (No idea why.) This map has been argued over more then any other map, running 146 pages of discussion at the time of acceptance. It started work December 4, 2006, you do the math if you want to figure out how long that is. If you want to see the monster that was it's topic look here: Clicky! The theme of the map is pretty obvious quickly and should feature gameplay most users are comfortable with. qwert is also working on Iwo Jima and WWII Western Front, hopefully they will be released at a much faster pace then this one took.
Valley of the Kings
cairnswk
cairnswk releases another map, With a startling 4 more maps on the way. This has to do with tomb robbing and Egyptian mythology. I think. I actually didn't follow it very much during development.

Montreal Revamp
WidowMakers
A couple things changed but I couldn't tell you off the top of my head. WidowMakers did this one. He revamped the Circvs Maximvs map as well if you forgot. This isn't as expressive as most of his works but is a major improvement over the muddy art of the original.
