In 2.2 you can expect a lot of changes regarding battlefield maps. Not only we have remastered all the existing settlements so they no longer have bugs like broken gate/palisade animations, pathfinding issues and units being deployed outside the city walls but also we have dozens of new custom tiles for the campaign map. There are also custom structures like small villages, houses, farms, temples spawning sometimes on the battlefield but these you can find on our twitter as they were already previewed (like this one). All of the maps you're going to see here you can actually find when playing campaign battles on specific tiles.
Wonders
Temple of Artemis

Colossus of Rhodes

Temple of Zeus at Olympia

Hanging Gardens of Babylon

Pyramids

Mausoleum at Halicarnassus

(we couldn't make custom settlement for this one and because of that the mausoleum isn't located inside the city)
Pharos

(same as with the Mausoleum at Halicarnassus, the Pharos isn't located at Alexandria, you can reach it when fighting a battle on Alexandria's port tile)
Stonehenge

Ports
(we have 47 of them, on the screens you can see 3-4)
Credits
Most of the models are ported from Rome 1 and from De Bello Mundi. xHolyCrusader did a great job doing all the wonders, both assembling them and mapping. I have fixed lots of issues in settlements maps as stated above. Ports maps were made 50/50 by xHoly and me. Pyramids were borrowed from Med 2 :X Stratmap wonders were placed on map by me.
