The 3rd Edition is folded like the 2nd Edition, but the large Metro Arrow logo has been removed from the top right corner and the boiler plate is featured again. The AoS Team logo is also present.
This edition also has a few more cubes present on the map than the 1st and 2nd. This change was inadvertent, and happened because the graphic revision was made using an earlier revision of the map. Discussion of this is present here: http://www.boardgamegeek.com/geeklist/1650/item/1647581#item1647581
