Notice if you look on the west side of the map. There is ice outside that game map. Therefore not part of the region.
If you look at Undella Town, The water is not frozen under the ice. They are hideing stuff most likely. I am hopeing for a Safarii Zone
There is also something new in the northern part of the western map. I am not sure what it is. It also looks like the Pokeleague structure in the northern east has changed some.
